Why Has the class ID Changed?

The correct class ID for Windows Media Player 7 and later is: clsid:6BF52A52-394A-11D3-B153-00C04F79FAA6.

Many places on the Internet it states that the class ID should be: clsid:22D6F312-B0F6-11D0-94AB-0080C74C7E95. This class ID is not the correct one, but it will work, because of backward comp ability. However, if you use this class ID you will not be able to use the new features added to the component.

Migrate to the new Windows Media Player 9 Series ActiveX control. The Player 6.4 control has fewer features and is less secure than the new control. In addition, support for the Player 6.4 control is being phased out.

Media Test Page

Can you tell me which tests didn't work (using Windows XP) on the Media Test Page here:

http://home.att.net/~cherokee67/mediatests.html

I have taken the page link down temporarily until it is fixed.

I've had multiple users, using both XP and 98SE, trying out the tests , and each user (depending on players) had a different experience. Using Windows 98SE, every page works for me.

Your media test page was replaced with other tests for WMP ActiveX and Quicktime plugins (many of your media tests are direct links to media files, not really plugin tests). I seem to remember my reasons for removing the page were problems with two or maybe three pages. If I remember right, one problem page was "Streaming MP3 File •• Black Magic Woman" which didn't work for me when it was an embedded m3u file. I see that it is "fixed" now, but it's a direct link to an m3u file (not really a test of an MP3 plugin). Another problem page was "Streaming QuickTime Movie •• Antony Shen" which gave me a missing plugin alert until I changed my Quicktime browser settings, MIME settings, to include "QuickTime image". I think there were more problems but I really don't remember the specifics. If you have any other questions about the page or want others to test it you should post to the MozillaZine forums.
