Though as has been pointed out by someone else earlier in the thread, 
the MIME types are attached to the container formats rather than the 
codecs. Seeing video/quicktime doesn't tell you what codec is used 
inside, and likewise video/x-msvideo.

Perhaps something like an Accept-codec: header (though preferably 
something more generic than that) is needed:

Accept-codec: audio/mp3, video/theora, audio/vorbis
