Problem Playing MPEG Files In Windows XP

[MustardJuice]

I recently started having a problem playing MPEG files in Windows XP. Here's
what I know and have done so far:

* The problem only occurs when I try to play an MPEG file from the Internet.
This includes clicking on a hyperlink to an MPEG file and using "File->Open
URL" through WMP. If I double-click on a file in Windows Explorer, it works
properly.

* I have tried using IE6, IE7B2, and Opera 8.5 - the problem persists
regardless of browser.

* I have tried reinstalling WMP10, downgrading to WMP9, and then upgrading
back to WMP10. I have also tried using Media Player Classic - the problem
persists regardless of media player.

* AVI, WMV, ASF, WAV, and other common media files all work just fine. It's
only MPEG files that don't work.


The exact problem is this: WMP will open and the MPEG file will be listed in
the playlist, but it won't play. WMP displays a single frame (I think the
last frame), but when I click the Play button, nothing happens. If I
right-click on the file in the playlist and go to Properties, the length of
the MPEG file is listed as 00:00.

I have a suspicion that my registry is somehow corrupted. Could someone
export their HKEY_CLASSES_ROOT\mpegfile tree to a .reg file and then post the
contents of that file?

Does anyone have any idea why this is happening?

MPEGFile shouldn't help at all with this - that's just how the file gets
associated to WMP and doesn't affect playback.

Is mcspmpeg.ax on your system? If not,

will help get this working.

Thanks for your post! It helped me solved the problem I was having.

I didn't have mcspmpeg.ax on my system per se; I had nikonmcspmpeg.ax, which
came with my Nikon PictureProject software. Once I uninstalled
PictureProject, everything fixed itself.

Thanks again!
