Use Windows Media Player 9 in Mozilla

Normally when you see an webpage that uses the Windows Media Player control in Mozilla of Mozilla Firebird it's shown with the old Windows Media Player control aka version 6.4 control.

With this registry fix you can now use the Windows Media Player 9 control. Either cut of the following text and save it into a wmp9.reg file and run it
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MediaPlayer\ShimInclusionList]

Or you can just click here to download the registry fix

It's already logged as a bug in bugzilla. See bug 193883.

phoenix.exe? For Firebird this should be MozillaFirebird.exe, or am I wrong?

The fix works in firefox 0.8, but i think that it is strange that it isn't has been fixed in the new builds?

Hmm.. i'm using firefox .8 and it still doesn't work.. To apply that to the registry i just save it to a text file and merge right?

I ran the registry fix that was listed and i'm having some issues with it, primarily with regards to streaming video, and switching back and forth from dialup to high-speed settings.

I watch news telecasts from usually in IE, however i decided to switch over the Firefox. However, due to high bandwitdth, the default setting with watching news telecasts is on dialup. When i switch to high-speed in IE, there are no issues. However, when i try to do the same in Firefox, it reloads the page, but it continues to stay as a dialup feed. Does anyone have any idea what i have to do so i can finally not use IE anymore?

It's an error with the site's JavaScript not the registry fix.

The problem I'm having (with a Firefox later than PR1.0) is, f.i., at

It was bringing up MP6.4 (mplayer2.exe).

So I merged in

Now it does bring up WMP9, but not quite correctly, still as if it was MP6.4, with full display format and the controls at mid-height.
And, of course, it says Ready, but it shows nothing, even if one hits Play.

My plugins, etc... are being pointed to by Firefox OK...
IE 6 works. So?

Dear Henrik,
With your registry fix for Windows Media Player 9/10 you solved a problem that nobody else could. After installing the update to 9/10 I lost pictures or sound and eventually both, not only in Mozilla but then in IE. After a month of trying everything I found this page. It cured the problem in both Mozilla and IE. It is not just the skin of WMP that is now correct, BOTH BROWSERS NOW FUNCTION with media Player. Thank you very much.

Looks like a similar entry needs to be created for Seamonkey 1.0

How do I save the file as wmp9.reg or how do I merge it into a wmp9.reg file?

Comment by Zach at June 5, 2006 04:38 AM | Permalink

Note... this fix works on wmp versions 10 and (I assume) 11 as well.

Where do i save it if i have wmp 10?

Comment by eric at August 24, 2006 01:24 AM | Permalink

Had the same problem. Wierd part was it only had a problem under one login account. All other users on the same machine had no trouble. Here's what fixed it.

Close WMP.
Open Windows Explorer.
Navigate to C:\Documents and Settings\[user]\Local Settings\Application Data\Microsoft\Windows Media\9.0
Delete all files in this directory.
Restart WMP.

Et Voi-la!
