      It doesn't go to Microsoft, it's just a cache of CDDB lookups you've done. AudioCatalyst does the same thing - but it's tracking not only what you play, but also what you rip to MP3. Surely, if you are looking for a conspiracy, that is where to look?

      This cache is just a performance enhancement, like your web browser maintaining a cache of pages you've visited. If anything, it improves your privacy: it makes it much more difficult for CDDB to track how often you play a particular CD.

      From the article:
      When a CD is played, the player downloads the disc name and titles for each song from a Web site licensed by Microsoft. That information is stored on a small file on each computer in the latest version of the software.

    If you read the article all this "database" is a copy from the CDDB records (or whatever CDDB is called these days) used for caching. You stick a CD in, it generates a checksum and asks CDDB for the artist/track listing and stores it locally, so it doesn't have to ask again later. As far as I'm aware, there isn't any sending of this database.

    It appears they extended to DVDs as well as CDs (just a bigger database I suppose).

    The article is a bunch of fluff for a functionality we've used for a long time with numerous programs such as XMCD, AudioCatalyst, etc etc. Microsoft adds it to media player and omg, privacy for getting the disc information for you. I'm pretty sure there's a button to turn it off.

      Serious privacy problems in Windows Media Player for Windows XP by Richard M. Smith

      http://www.ComputerBytesMan.com

      February 20, 2002

      Introduction
      ============
      I found a number of serious privacy problems with Microsoft's Windows Media Player (WMP) for Windows XP. A number of design choices were made in WMP which allow Microsoft to individually track what DVD movies consumers are watching on their Windows PC. Thesep problems which introduced in version 8 of WMP which ships preinstalled on all Windows XP systems.

      In particular, the privacy problems with WMP version 8 are: - Each time a new DVD movie is played on a computer, the WMP software contacts a Microsoft Web server to get title and chapter information for the DVD. When this contact is made, the Microsoft Web server is giving an electronic fingerprint which identifies the DVD movie being watched
      and a cookie which uniquely identifies a particular WMP player. With this two pieces of information Microsoft can track what DVD movies are being watched on a particular computer. - The WMP software also builds a small database on the computer hard
      drive of all DVD movies that have been watched on the computer. - As of Feb. 14, 2002, the Microsoft privacy policy for WMP version 8 does not disclose that the fact that WMP "phones home" to get DVD title
      information, what kind of tracking Microsoft does of which movies consumers are watching, and how cookies are used by the WMP software and the Microsoft servers. - There does not appear to be any option in WMP to stop it from phoning home when a DVD movie is viewed. In addition, there does not appear any
      easy method of clearing out the DVD movie database on the local hard drive.

      Technical Details
      =================

      When a DVD movie is played by the WMP, one of the first thing that WMP does is to query via the Internet a Microsoft server for information about the DVD. The query is made using the standard HTTP protocol that is also used by Web browsers like Internet Explorer or Netscape Navigator. Using a packet sniffer I was able to observe WMP making these queries to a Microsoft server each time a new DVD movie was played. The packet sniffer also showed the movie information which was returned to WMP by the Microsoft servers.
      The first HTTP GET request sent by WMP identified the movie being played.

      For example, an HTTP GET request is made for this URL for the "Dr. Strangelove" DVD: http://windowsmedia.com/redir/QueryTOC.asp?WMPFrie ndly=true&locale=409&
      version=8.0.0.4477&
      cd=1E+ 96+1B1E+30D9+42D8+5D61+783E+9083+C49C+F0C8+1 151E+13CF9+
      15812+16C5D+1A04F+1BF2D+1ECB7+212E1+2 2E48+25724+27 E9D+2A91A+
      2D0E6+2F451+38367+3CF64+4A4D6+4C001+4D 517+4E51B+4F DBC+51F74
      The hex numbers at the end of the URL are an electronic fingerprint for the DVD table of contents which uniquely identify the "Dr. Strangelove" DVD. This URL is sent to WindowsMedia.com, Microsoft's Web site dedicated to the WMP software. The HTTP GET request also included a ID number in cookie which uniquely identifies my WMP player.
      Here's what this cookie looks like: MC1=V=2&GUID=CA695830BB504D399B9958473C0FF086
      By default, this cookie is anonymous. That is, no personal information is associated with the cookie value. However, if a person signs up for the Windows Media newsletter, their email address will be associated
      with their WindowsMedia.com cookie.

      For example, when I signed for the Windows Media newsletter, the following URL was sent to Microsoft servers: http://windowsmedia.com/mg/Newsletter.asp?eNws=rms @computerbytesman.com&
      format=HTM

      The same windowsmedia.com cookie value will be sent back to Microsoft servers when signing up for the newsletter and when a DVD moive is played. In addition, using various well-known "cookie synch" tricks, an email address can be associated with a cookie value at any time. Also when subscribing to the Windows Media newsletter, I was encouraged
      by an email message from the Microsoft newsletter department to create a Passport account based on my email address. In theory, yet more personal information from Passport could be matched with what DVD movies I have
      watched. There is no evidence however that Microsoft is making this connection. The WindowsMedia.com cookie was assigned to my computer the first time I ran WMP. The lifetime of the cookie was set to about 18 months. This cookie gives Microsoft the ability to track the DVD movies that I watch
      on my computer.

      After a series of redirects from the WindowsMedia.Com server, information about the "Dr. Strangelove" movie was returned in this XML file: http://services.windowsmedia.com/amgvideo_a/templa te/QueryDVDTOC_v3.xml?
      TOC=90a1b0d1571524ea

      WMP extracted movie information from this file and then added this information to a database file, named wmplibrary_v_0_12.db, which is located on my hard disk in the directory " C:\Documents and Settings\All
      Users\Application Data\Microsoft\Media Index". I didn't see any method
      of removing movie information from this file, so it appears to me that the file keeps a complete record of all movies watched that have ever been watched on my computer. Because as of Feb. 14, 2002 the Windows Media privacy policy is silent about what is done with DVD information sent to Microsoft servers by the WMP software, we can only speculate what Microsoft is doing with the
      information. Here are some possibilities: - Microsoft can be used DVD title information for direct marketing purposes. For example, the WMP start-up screen or email offers can be
      customized to offer new movies to a WMP user based on previous movies they have watched. - Microsoft can be keeping aggregrate statistics about what DVD movies are the most popular. This information can be published as weekly or monthly "top ten" lists. - Microsoft might be doing nothing with the DVD information. (In my discussions with Microsoft, I was told this option is their current practice.) Note: The Video Privacy Protection Act of the United States prevents
      video rental stores from using movie titles for direct marketing purposes. The letter of this law does not apply to Microsoft because
      they are not a video rental store. However, clearly the spirit of the law is that companies should not be using movie title information for marketing purposes.
      Recommendations
      ===============

      I believe that the Microsoft should remove the DVD movie information feature from WMP version 8 altogether. The value of feature seems very small given that almost all DVD movies include a built-in chapter guide.
      In addition, the Microsoft movie information feature is not available when DVD movies are shown in full-screen which is how DVD are typically watched. If Microsoft feels that this feature is important to leave in WMP, then I think it should be turned off by default. The feature can be made privacy-friendly very easily, by having WMP never send in cookie information with movie title requests. This change will prevent
      Microsoft from tracking individual movie viewing choices.

    As part of downloading the information about songs and movies from the Web site, the program also transmits an identifier number unique to each user on the computer. That creates the possibility that user habits could be tracked and sold for marketing purposes.

    The same company that assigns you a unique number for the downloads you make also has the database you were required to register with in order to activate your WindowsXP. Manipulated properly it would be a rather simple task to match a real name and address with what you watch on media player - especially if this 'unique number' and the registration number for XP were one and the same.

    And note that Microsoft hasn't ruled out using the data for marketing purposes.

    OK, yes WMP from version 7 onwards is a nasty beast.

    This article is mostly scare tactics, as ever since the beginning of time there's been a file named CDPLAYER.INI in the windows folder that stores CDDB info. A local cache should actually enhance your privacy as it will reduce calls to central servers when you play your CDs or whatever.

    WMP 7+ however doesn't use this file. If you look in your Windows folder again, you'll notice a couple of files named WMSysPrx.prx and another one named similarly that actually stores the song database. That's how the 'media library' feature works, it's all stored in there -- you would expect a program that catalogues songs to store a list of media played somewhere, wouldn't you?

    It's true WMP does track how many times you play a song. But discovering the fact isn't aexactly a journalistic coup, it's listed in the program itself. Look in the 'Media Library', this is listed along with all the rest of the ID3 information (at least in WMP 7)... not exactly a huge secret. I have never heard of MS sending this info off to its site before... that sounds a lot like how Real got into trouble a few years back, and also a lot like a very inventive and paranoid reporter. If you're worried, delete those files mentioned above every so often.

    The unique ID is more interesting. I really recommend turning this off in your WMP options, as it's only really useful if you're buying proprietry WMA files online... and somehow I don't think many slashdotters will be doing that ;).

    The worst part is that it opens up the recently discovered SuperCookie exploit in which websites can embed a player in a page and get it's ID number. Since it's globablly unique and installed on most computers, it's a great way of tracking users who are savvy enough to turn off cookies.

    So nuke the ID feature quickly from your player options... even if you use *AMP to play your sounds, you could still be vulnerable to this.
