People out there are already doing the exact same thing with .ogm
('ogg movie'). This is not a new suggestion.
Let's leave extentions out of it, really... it's a discussion of MIME.
Let the people with OSes who care what extention a file has use the
extention they want. This is a fight I'm not going to get involved in.
(There's a specific reason; only Windows does its file determination
according to extention and extention only. Putting a file extention
in the spec is a slap in the face to everyone else, especially those
who pride themselves on running 'smarter' systems that use mime (Be),
file metadata (MacOS) or file magic (UNIX). We can *suggest* an
extention, or let the masses decide. The masses will converge on an
answer just fine by themselves; there's no standards body demanding we
do it for them.)
As for audio players playing video, the current generation of media
players clearly combine the two. Quicktime, WMP and Real are all
audio/video, and the trend continues in that direction whether it's a
good idea or not. The only standout exceptions are WinAMP (which will
play video with plugins) and iTunes (which I honestly expect to play
video someday soon if it doesn't already. Music video anybody?).

With this I agree. MIME is clearly application-oriented (not media
type oriented, as another list member insightfully pointed out). It's
status quo to have audio/xxxx and video/xxxx and I think for good
reason. The trend is away from audio-only players (at least for the
mass of users) but for now, the world is this way. With
application/xxxx, we have all the bases covered for the forseeable
