That sounds like a third party player corrupted WMP's registration. What
third party players are on the box?
Off the top of my head, the key elements in this registration are:
HKEY_CLASSES_ROOT\ MIME\Database\Content Type
for that type (in this case, likely video/mpeg ). There's a CLSID value
there, probably {CD3AFA89-B84F-48F0-9393-7EDC34128127} .
Then under
HKEY_CLASSES_ROOT\ CLSID\{CD3AFA89-B84F-48F0-9393-7EDC34128127}\ProgID
Under the MIME content type there was an extension, likely .mpg . You then
go to
HKEY_CLASSES_ROOT\.mpg
and look at the default value there. That on a vanilla Vista system is
(IIRC) WMP11.AssocFile.MPEG which is at
HKEY_CLASSES_ROOT\WMP11.AssocFile.MPEG .
The subkeys under there (as indicated by the WMP11 name) should be
WMP-specific.
Your problem usually comes about when one of those elements in the chain are
corrupt.
