The Top 10 List for New Yahoo U.S. Head Ross Levinsohn–the BoomTown Rules

Dear Ross,

Perhaps more than anyone, BoomTown is thrilled to have you back in the Internet ops game, after several years on the sidelines.

Besides introducing an exciting new character and plotline into the daily digital drama set in Sunnyvale, Calif.–kind of like when one of Alexis Carrington’s ex-husbands returned after a bout with amnesia on “Dynasty”–it’s clear you are not going to be a shrinking violet.

Plus, you know how to handle drama after all those crazy years herding digital cats at News Corp.’s MySpace.

In other words: Nobody puts Ross in the corner!

But it’s a very big job you have, running both Yahoo’s massive media properties, as well as its giant sales organization–especially after all those years of long lunches as a venture investor.

Thus, I prepared a short list for you–kind of a Yahoo cheat sheet–to cut out and put in your cyber-wallet, and pull out if the need should arise:

10. If you have any internal emails, product roadmaps, acquisition plans and–especially–juicy memos, please immediately forward them to kara@allthingsd.com via the secret Gmail account every Yahoo staffer has. (Don’t worry, everyone does this! Really!)

9. If anyone offers you $31 a share for Yahoo, take it.

8. If someone asks you the question, “What is Yahoo?”: Run for the hills.

7. If anyone tries to drag you back to Sunnyvale from Los Angeles, resist, even after what happened to Lloyd Braun. There are no advertisers nor any significant digital media folks in Silicon Valley, however much anyone tells you there are.

6. If a billionaire shareholder activist named Carl whom you used to canoodle with about taking over Yahoo calls, please refer to No. 8.

5. If you can locate where Yahoo co-founder and former CEO Jerry Yang has gotten to of late–he has been sighted at Yahoo “strategery” meetings and playing golf with advertisers–please send his coordinates to kara@allthingsd.com. I am not a stalker. Well, only a little bit.

4. If you have to ask who Judy is, you have already lost, because Judy is actually in charge at Yahoo. (By the way, since you are both from Jersey, work that angle hard!)

3. If a smiley, cheekboned, Don Draper-looking dude calls from AOL wanting to do a “reverse merger” and offers a ride on Air Tim to discuss it, please refer to No. 8.

2. If you feel frustrated and have the need to utter naughty words and curses, stifle it! That’s a job for the CEO!

1. Ignore me.*

* At your peril.

Digg Lays Off More Than One-Third of Staff as It Seeks to Cut Costs

Digg has announced it is laying off 25 of its 67 staffers today, part of an attempt by the San Francisco social news discovery site to rationalize its costs.

In an interview with BoomTown this morning, CEO Matt Williams noted that “the burn rate is just too high” for the company.

“We need to reset, in terms of stategy and get back in a start-up mode,” said Williams, referring to the recent turmoil at Digg, related to management upheavals and product snafus. “The cost structure is not in line with our business.”

Earlier today, I reported that Digg’s Publisher and Chief Revenue Officer Chas Edwards was departing to take a similar job at a photo-tagging advertising start-up called Pixazza.

Edwards is just one of many such issues at Digg, where Williams seems to have stepped into a very big mess since he arrived just six weeks ago.

That includes dealing with a new version widely derided by its passionate and opinionated users, for which Williams quickly apologized.

“I knew it was going to be a big job in terms of a product turnaround,” said Williams. “I think the users love Digg and want to see us succeed and we ultimately let them down.”

Williams said his goal was to get to profitability in 2011, which required the employee layoffs.

From there, he said, “We will be on good footing to be more innovative.”

That would be a nice change of pace, given Digg’s fall from Web 2.0’s hottest start-up to one that seems only to falter.

Those stumbles have included a failed sale to Google, previous layoffs and general product drift.

Here is a blog post that Williams just put on the news aggregator’s site:

Just wanted to share an important development at Digg. Here is a copy of an e-mail that I sent to the staff today…

Team,

When I joined Digg six weeks ago, we set an immediate focus on improving the web site. We listened carefully to user feedback and started making changes to generate momentum in our business.

As I mentioned in one of our first all-hands meetings, another top priority was to take a hard look at the entire business, across product, sales, and operations. Through the time I have spent with each of you, I’ve been impressed by the commitment and enthusiasm you’ve shown. I’ve also learned a great deal about what is working well at Digg, and what is broken.

Many things are working well. The team is listening and acting quickly on the feedback from our passionate community. We’ve been able to deliver nimbly on the new platform, with over 100 bug and feature releases to the web site in the past two months. Our Diggable ads product has seen a notable increase in use by advertisers and clicks by users.

Unfortunately, to reach our goals, we have to take some difficult steps. The fact is our business has a burn rate that is too high. We must significantly cut our expenses to achieve profitability in 2011. We’ve considered all of the possible options for reduction, from salaries to fixed costs. The result is that, in addition to lowering many of our operational costs, I’ve made the decision to downsize our staff from 67 to 42 people.

It’s been an incredibly tough decision. I wish it weren’t necessary. However, I know it’s the right choice for Digg’s future success as a business. I’m personally committed to help find new opportunities for everyone affected by the transition. Digg’s Board members have also offered to help find placements within their portfolio companies.

Let’s please use today to show our sincere appreciation for our friends and colleagues who will be moving on. Tomorrow, we’ll go forward with a new strategy for Digg.

Matt

Gphone vs iPhone, which is better?

As iPhone is the most talked about smart phone on the planet and it has won millions of hearts of users by his multi-touch screen and other powerful/beautiful design. Of course, iPhone has brought so much money for Apple.
On 23rd, Sep 2008 Google released G1 and claimed that they will have a share of the big market of smart phone.
So, which is better about iPhone and G1? That maybe asked by many people who want to buy a new phone. Here I will give some of opinion about G1 and iPhone.
I will compare these two phones in three aspects, hardware, software, and their performance as a media player.

Gphone vs iPhone

Part 1: Hardware.

1. The price and storage memory
First, the price and storage memory is what I concern most, for iPhone $199 8GB, $299 16GB, for G1 $179 1GB. When you see this you will say G1 is $20 lower than iPhone but G1 is only 1GB and you will pay another $40 for an 8GB SD Card. So I think iPhone win in this round.

2. Appearance
iPhone is 133 grams/4.7 ounces and G1 is 158 grams/5.57 ounces. G1 is taller while iPhone is thinner (G1: 117.7*55.7*17.1, iPhone: 115.5*62.1*12.3).

3. Mobile Network
For mobile Network, they both have Quad Band GSM/EDGE UMTS, but G1 uses T-Mobile-only US 3G and iPhone uses AT&T-only US 3G.

4. Touch screen and input
About touch screen display, iPhone has Multi-touch 3.5 480*320 163 ppi, but G1 does not support mulit-touch. And in input aspect, G1 uses keyboard, Trackball, 6 buttons and touch screen, while iPhone has home button and multi touch screen.

5. Expansion
In expansion ports, G1 uses SD, ExtUSB(USB+audio) but iPhone has headphone, Dock connector (USB+ audio, video, remote). They have the same wireless WiFi 820.11b/g Limited Bluetooth 2.0 EDR.

6. Others
About hardware, the two phones perform almost the same and the only big difference is the iPhone uses multi-touch screen and G1’s camera is better than iPhone. And iPhone has a 1400Ah battery with 300 hours standby time but G1 only has a 1150Ah battery with 5 hours talk time and 130 standby.

Part 2: Software.

iPhone and G1 are both using Webkit as their browser engine. In media playback aspect, iPhone supports music, audiobook, video, streaming, downloads and rental, while for G1, only music playback. G1 has Android Market as its third party software store while iPhone has iPhone app store. G1’s platform is Modified Java development and iPhone uses Cocoa Touch.

Part 3: Their performance as media player.

G1 supports H.264, 3GPP, MPEG4, Codec 3GP video and MP3、AAC、AAC+、WMA、MPEG4、WAV、MIDI、REAL、AUDIO、OGG audio formats.
iPhone supports AAC，Protected AAC，MP3，MP3 VBR，Audible (formats 1, 2, 3), Apple Lossless, AIFF, WAV audio formats and H.264 (up to 1.5Mbps), MPEG-4 (up to 2.5Mbps) 640*480, 30fps, AAC-LC (up to 160 Kbps), 48kHz dimensional sound .m4v, .mp4 and .mov format.

Amazon MP3 Store allows you to download 6 million songs without the DRM protection, 89 cents per song. It is similar with the Apple iPhone, you need to pay for the video and audio sources on the Apple store. But how to get free sources for your G1.

For iPhone and G1 you can buy songs and videos from store, which is really expensive, and you can also make songs and videos for your iPhone and G1 by yourself, you just need to convert your DVDs and videos to mp4 format and then you can put them easily to your iPhone and G1.

Here I recommend you Aiseesoft DVD Converter Suite, it includes Best DVD Ripper, Total Video Converter and iPod to Computer Transfer.
For Mac user, I recommend you Aiseesoft DVD Converter Suite for Mac, it includes DVD Ripper for Mac and Total Video Converter for Mac.

A Nerd by Any Other Name Would Be as Geek–Bing Gordon Waxes Poetic and More at the SFund Launch

BoomTown will admit it: I am a social party pooper.

In any case, here is a lovely video I did yesterday while at the launch of the sFund.

The sFund is a $250 million fund for social start-ups, whose partners include Kleiner Perkins, Amazon, Facebook, Comcast, Liberty Media, Zynga and Allen & Co.

The event participants included, as you can see above, Silicon Valley power VC John Doerr, Amazon CEO and founder Jeff Bezos, Facebook CEO and co-founder Mark Zuckerberg, Zynga CEO and founder Mark Pincus, and VC Bing Gordon.

All are also below.

At the end of the presentation to the press, the sFund’s new majordomo, Gordon (who looks like a clean-shaven version of Hagrid from “Harry Potter”), took to the stage and read a very unusual poem about entrepreneurs, which I recorded for posterity. After which, he took on a video interview.

Exclusive: Yahoo’s Head of Mobile, North America Leaves, As U.S. Unit Reorgs

Today at Yahoo’s third-quarter earnings conference call with Wall Street analysts, Yahoo CEO Carol Bartz said tersely of a flood of exec departures at the Silicon Valley Internet giant:

“Some people leave, some get promoted and some good people arrive.”

Yes, indeedy, and this afternoon, it was David Katz’s turn to say goodbye. He was Yahoo’s VP for Mobile, North America. (He is pictured here and you can read his bio here.)

The move, said sources, is part of a reorganization in the wake of the departure of David Ko, SVP Audience of Mobile and Local, North America.

He was replaced by Raymond Stern, who also heads business development.

If it seems a little confusing, it is because it is.

But there is all kinds of management rejiggering discussions going on after the additional departures of U.S. head Hilary Schneider and Media VP Jimmy Pitaro.

Mobile is an important arena for Yahoo, as Bartz also stressed in the call today.

HP Chairman Lane Smacks Back at NYT’s Nocera: The Poison Pen Letter!

Who would have thought that the enterprise business would be this interesting?

But the continuing mishegas between Hewlett-Packard (HP), Oracle (ORCL) and the controversial move between the companies by exec Mark Hurd has now dragged in the New York Times (NYT).

Specifically, its star business columnist Joe Nocera, who penned a scathing piece a few days ago about the recent appointment of former SAP (SAP) top exec Léo Apotheker as CEO of HP to replace Hurd.

Wrote Nocera, as he wound up his fastball:

“Still, having written two unflattering columns recently about the H.P. board, I was inclined to take a pass on Mr. Apotheker’s hiring. But then I learned something about him that caused me to shake my head in disbelief.”

The thrust of Nocera’s column about a lawsuit over intellectual property theft between SAP and Oracle: Don’t throw stones at Hurd when you have such a dirty glass house.

But I am synopsizing, so here is the letter incoming HP chairman Ray Lane–who, by the way, once worked as president at Oracle until he and CEO Larry Ellison had a falling out.

You know, the non-shy and non-retiring Larry Ellison who has been sending constant verbal stink bombs over to the HP board of late–most recently at Apotheker–and who hired Hurd.

Folks, you cannot make this stuff up.

Here’s Lane’s letter (I removed all the email addresses) to the Times:

From: Ray Lane
Sent: Monday, October 11, 2010 8:59 AM
To: XXX
Cc: XXX
Subject: Letter to the Editor, NY Times

To the Editor:

Joe Nocera’s column, “A Double Standard at H.P.,” (October 9, 2010) grossly mischaracterizes the facts about why Mark Hurd had to leave HP, why the HP Board hired Léo Apotheker as CEO and the reason Oracle is trying to draw Mr. Apotheker into its lawsuit over TomorrowNow.

First, the lawsuit on TomorrowNow: Mr. Nocera concedes the suit between Oracle and SAP (and its now-shuttered subsidiary, TomorrowNow) is old news. Oracle has been litigating this case for years and has never offered any evidence that Mr. Apotheker was involved. It didn’t even deem him relevant enough to the case to include him on a list of witnesses for trial–until, that is, Mr. Apotheker was named CEO of HP and Oracle had other motives to try to tie him to the case.

The facts are: TomorrowNow was never under Mr. Apotheker’s supervision. The conduct in question at TomorrowNow occurred before Mr. Apotheker became CEO of SAP. And, it was Mr. Apotheker who, as CEO of SAP, shut down TomorrowNow. Mr. Nocera’s reporting on the case is sharply contradicted by that of an independent industry analyst–someone with real knowledge of the industry and the facts–who makes clear that Mr. Apotheker was not involved (http://ematters.wordpress.com/2010/10/09/setting-the-record-straight-oracle-sap-tomorrownow-and-the-nyt/).

As for the reasons why Mr. Hurd left HP: no Board can retain a CEO who violates the trust and integrity needed to lead a public company. Even Mr. Hurd publicly acknowledged that he failed to uphold those necessary standards. In the press release announcing his departure, he said that “… there were instances in which I did not live up to the standards and principles of trust, respect and integrity that I have espoused at HP…I believe it would be difficult for me to continue as an effective leader at HP and I believe this is the only decision the board and I could make at this time.” (Emphasis added.)

The bottom line is: Mr. Hurd violated the trust of the Board by repeatedly lying to them in the course of an investigation into his conduct. He violated numerous elements of HP’s Standards of Business Conduct and he demonstrated a serious lack of integrity and judgment. The Board was unanimous in its decision that he must go, including the seven directors Mr. Hurd recruited to the Board. These directors would not have acted unanimously to remove Mr. Hurd for “piddling expense account problems” as Mr. Nocera suggests. I was named to the Board after Mr. Hurd’s departure, but having carefully reviewed all the facts, it is clear to me the HP Board made the right decision. Had I been on the Board at that time, there’s no question I would have voted the same way. The Board simply had no alternative.

In hiring Léo Apotheker, HP’s Board turned to a principled leader of outstanding personal and professional integrity. He is an experienced, strategic thinker with the passion, global experience and operational discipline to realize our company’s enormous potential. Those are the qualities HP needs in a leader to move the company forward, and Mr. Apotheker is ideally suited to do that.

Sincerely,

Ray Lane
Incoming Non-Executive Chairman of the Board of Directors

Three Ways to Download Music To Your Zune Player

There are several ways you can download your Zune movies, Zune music videos, Zune MP3's and Zune software to your Zune player.
1) The first is from the Microsoft Zune Marketplace and other Pay-Per-Download Sites which have movie downloads, music downloads, music video downloads, and more. The problem with downloading Zune files from places like Microsoft Zune Marketplace is the cost. The Microsoft Zune Marketplace charges a monthly subscription service called the "Zune Pass" with unlimited downloads for $14.99 per month. The pay-per-download sites charge on the average about $1.00 per Zune download. So, with a Zune player that has a 30 gigabyte hard drive whic allows users to store up to 7,500 Zune MP3s, 2,500 pictures or 100 hours of Zune movies and Zune music videos, that is going to cost a fortune to fill up.

2) WiFi - Microsoft Zune players has a technology called WiFi which allows friends and family to share Zune music, Zune movies, Zune software, pictures and Zune music videos both effortlessly and wirelessly. If you have a cool picture or something you found on a zune download site you can share it easily. Anytime you come in close range of another Zune player you can connect to that Zune player via WiFi and share your Zune downloads. The only drawback is you can only play a shared song only 3 times before it is deleted although, pictures are saved and can be viewed many times. It's a nice feature but needs improvement.

3) The third way is by ripping your music CD's to your Zune player. The definition of ripping means converting CD music files to a file format usable by your Zune player which is either in MP3 or WMA file format. After doing this, all you need to do is plug your Microsoft Zune player into your computer with a USB cable and transfer the ripped music files to your Zune player using the provided Zune software.

1. Put the music CD that you want ripped into your PC.
2. After the media player opens. Select the song you would like to copy and click on RIP.
3. Save the song you just ripped to a folder of your choice.
4. Plug in your Zune Player to your PC using the USB Cable. The Zune Software will automatically search for music that you saved in the folder on your PC. Select the files you want and manually drag and drop them into your Zune player's music folder.

VC Ben Horowitz Takes Aim at HP Critics (Are You Listening, Larry and Jack?)

Today, in a sharply worded post, titled “In Defense of Standards, Ethics, and Honest Financial Reporting at Hewlett-Packard,” prominent venture capitalist Ben Horowitz took to his blog to shoot back at the plethora of critics of the Hewlett-Packard board for their conduct related to the controversial jettisoning of CEO Mark Hurd.

That came after Hurd admitted to falsifying expense reports related to an outside contractor he had hired, who later alleged sexual harassment. Those charges were dropped after Hurd settled with the woman, named Jodie Fisher, but before HP could complete an investigation.

Since then, the board has been under fire from Oracle CEO Larry Ellison, who hired Hurd as the database giant’s president; and former GE head Jack Welch, who laid into the HP board this week.

Now Horowitz has fired back and here’s a taste of his ire, which is aimed at execs, the media and more:

If a CEO is prone to compromise for any reason, he will have every reason. This time it was his expense report. Next time will it be a marginal accrued liability? A deal that came in at 12:01 am on the last day of the quarter? This is a slippery slope that a public board simply cannot tolerate.

And:

Who is Jodie Fisher? According to press reports, Fisher is a former Playboy model, reality show contestant, and softcore porn movie actress with no work history relevant to her job with HP. She was hired by Hewlett-Packard and paid up to $5,000 per meeting to meet with Fortune 50 CEOs.

The mainstream press has reported these facts as mundane, ordinary, and hardly worth concern. I disagree. HP employs over 300,000 people. Every single one of HP’s employees is keenly interested in the qualities, skill sets, and behaviors that HP values most. Financial compensation and access to the CEO are the most important ways that HP communicates what it values to its employees. Jodie Fisher had more access to the CEO and was paid more than 99.9% of HP’s workforce, despite having no traditional qualifications.

It’s important to note that this was not Hurd paying for his personal extracurricular activity out of his own pocket. This was the Hewlett-Packard Corporation paying a softcore porn movie star with no relevant work experience more than it pays Harvard graduates with 20 years of industry experience. This was the company spitting in the face of the people who worked hard and sacrificed every day to help the company win in the market. It was completely and categorically unacceptable.

And:

There are many who take the view that business is singular in purpose–to increase shareholder value. They further take the position that constraining that purpose in any way is inefficient and counterproductive. The mainstream press seems to have broadly adopted this position in its attacks on HP. The Wall Street Journal Op Ed page even complained that businesses were being held to an unfair standard when compared to politicians.

I do not subscribe to this view. Running our companies with no moral or ethical standards is bad for society, bad for the country, and ultimately leads to criminal behavior.

So, what do you really think, Ben?

Horowitz does have an interest in the situation, which he discloses clearly at the top of his piece: His longtime business and now venture partner is HP board member Marc Andreessen.

And the Silicon Valley soap opera continues…

Yahoo Acquires Ad Start-Up Dapper

Yahoo doesn’t just shed top execs–it actually buys stuff related to its core online advertising business!

Thus, today, it announced the purchase of Dapper, an ad creation and optimization start-up.

Dapper, Yahoo (YHOO) said, “enables advertisers and agencies to quickly and easily build dynamic ad creative, leveraging data to automatically show the right product, offer, or message with each impression.” Which means it’s similar to Teracent, the ad optimization startup that Google (GOOG) bought in November 2009.

Dapper is based in San Francisco and has received $3 million in funding from Accel Partners and entrepreneur Mitch Kapor.

Terms of the acquisition were not released.

Here is the official Yahoo press release:

Yahoo! to Acquire Dapper; Extends Leadership in Display Advertising with Dapper’s Ability to Drive Performance and Efficiency with Creativity and Science

SUNNYVALE, Calif.–October 5, 2010 –Yahoo! Inc. (NASDAQ: YHOO) today announced the company has signed a definitive agreement to acquire Dapper (www.dapper.net), a technology platform providing dynamic display ad creation and optimization. Dapper enables advertisers and agencies to quickly and easily build dynamic ad creative, leveraging data to automatically show the right product, offer, or message with each impression. Dapper’s capabilities combined with Yahoo!’s already deep consumer insights will further enhance Yahoo!’s ability to deliver customized and relevant advertising.

“Yahoo!’s unique combination of Science, Art and Scale connects advertisers with consumers in ways that drive results,” said Frank Weishaupt, VP, North America Ad Marketplaces at Yahoo!. “Smart Ads will continue to be an important component of display advertising and the acquisition of Dapper will help Yahoo! to more efficiently deliver dynamic and personalized ads for customers across more of our network.”

The acquisition builds upon Yahoo!’s current display advertising leadership and will accelerate the adoption of Yahoo! Smart Ads. Yahoo! currently partners with Dapper, along with others in this space, and owning this technology will help the company deliver innovative solutions to an even broader range of advertisers and integrate dynamic ad serving into key Yahoo properties. Yahoo! is committed to the Smart Ads program and remaining open to working with innovative third parties in addition to providing a proprietary solution with the acquisition of Dapper.

“Yahoo!’s product strategy is focused on creating engaging and meaningful experiences that keep users entertained and informed,” said Dev Patel, VP, Advertiser and Publisher Solutions at Yahoo!. “Utilization of consumer insights to deliver relevant consumer and advertiser experiences are built into our technology from inception and Dapper’s capabilities will further enhance the experiences we deliver.”

Exclusive: Yahoo’s David Ko to Head Mobile at Online Gaming Powerhouse Zynga

David Ko (pictured here), who just announced he was leaving Yahoo as head of its powerful U.S. Audience unit, is taking a job heading mobile efforts at hot social gaming start-up Zynga, according to sources.

The move comes only a day after Jimmy Pitaro, who also departed his job as SVP of Media at the Internet giant last week (working under Ko, in fact), landed at Disney (DIS) as the new co-president of its Internet division.

For Zynga–the fast-growing San Francisco-based maker of such online hits as Farmville and Mafia Wars that got its start on Facebook–mobile is becoming a critical new platform for growth, as consumers use a variety of increasingly functional mobile devices, such as smartphones and tablet computers.

It’s also the fastest growing area internationally, where mobile phones are more widespread and where Zynga is seeking its next spurt of growth.

Sources said Zynga had been pursuing Ko for months.

Before heading the Audience unit at Yahoo (YHOO), Ko ran its mobile operations, which included heading product development, making distribution deals and more.

Under Ko, Yahoo’s mobile efforts first centered on building apps for smartphones, such as the Apple (AAPL) iPhone, but shifted to encompass more of its copious content assets.

Ko, who worked in a variety of areas at Yahoo, took over as SVP of Yahoo Mobile in 2009 after Marco Boerries left as EVP of the Connected Device Division, which now does not exist under that name.

Ko had also run Yahoo’s mobile business in the Asia-Pacific region.

According to one of Ko’s old Yahoo bios, he previously worked at Salomon Smith Barney as a senior associate and analyst. He is a graduate of New York University’s Stern School of Business.

Ko, who lives in San Francisco with his family, the bio notes, inexplicably “enjoys reading tech blogs.”

In his new job, as SVP of Mobile at Zynga, he will report directly to CEO Mark Pincus, sources said.

How to share the iTunes Music and videos between two computers for free

Some people may meet that situation: You and your brother both have iTunes library under the same credit card account. Occasionally, you want to get the same song, however you wouldn't want you both to pay the $0.99 where virtually the same account is purchasing the song twice. So how can you and/or he download the songs from each other once it's purchased on a single computer? This is a guide to tell you how to share iTunes Music and videos between two computers such as sharing iTunes Music and videos between Windows PC and Mac OS X, sharing iTunes Music and videos between Mac OS and Mac OS X and sharing iTunes Music and videos between Windows PC and Windows PC

Step 1, Networking computers.
If you want to share iTunes videos and music between computers, you need to network PC and Mac first.
If you do not know how to Network Windows with Mac OS X, go there:
Networking Windows (2000/XP/2003*) with Mac OS X (10.3/10.4)
Information you will need to know
1.The IP Address of your PC (Start > Run > CMD {return} > "ipconfig" {return})
2The IP Address of your Mac (Applications > Utilities > Terminal {Run app} > for ethernet connection "ipconfig getifaddr en0" {return} or for wireless "ipconfig getifaddr en1" {return})>
3.The workgroup the PC is in (Right click on My Computer, select Properties, and select the Computer Name tab)

System Configuration
It is important that the account you log in with on your XP system has a password set, if it does not you will not be able to login to your Windows share from OS X. You need to put your Mac in the same workgroup as your Windows PC. To do this open "Directory Access" (Applications > Utilities > Directory Access). Click on the padlock in the bottom left corner to make changes; you will be prompted for your password. If "SMB" is not ticked off, then tick it off. Select "SMB" and hit the "Configure…" button. Now enter the name of your Windows workgroup. In my case the name is "AD".

Share iTunes videos between pc and Mac, iTunes videos from pc to Mac

Share iTunes videos between pc and Mac, iTunes videos from pc to Mac

Setting up the PC to share files
You need to create and share a folder on your PC that you will then access from your Mac. To do this create a folder (or select and existing one) right click on it from Windows Explorer and select "Properties". Select the "Sharing" tab and share out the folder. I'd recommend you use a one word name for the share. For example "Mac", not "Apple Mac Share", it just narrows the risk of complications.

Share iTunes videos between pc and Mac, iPod videos from pc to Mac

Share iTunes videos between pc and Mac, iPod videos from pc to Mac

Setting up the Mac to share files
Open "System Preferences" (Applications > System Preferences). Go to "Sharing" under "Internet & Network", and tick off "Windows Sharing", and if it doesn't start by itself, click "Start". This will share out your entire home folder.

iTunes videos from pc to Mac

If You're running Tiger (10.4), you will also need to click the "Accounts" button and tick off the box next to your account name so that OS X knows to share out your particular home folder.

iTunes videos from pc to Mac

Step2, Go to preferences, under the sharing tab, enable "Share library..." and "Look for shared libraries..." on both computers.
Select the items you want to share. share iTunes videos and music for free

It will show up in iTunes' side panel:
share iTunes videos and music for free

To require users to enter a password before they can see your shared items, select "Require password" and enter a password.
You will need to authorize both computers to play purchased content however. You may authorize up to 5 Machines per iTunes Music Store account.
