Note that both the extensions given to .mov and .avi imply that they're
movie formats, which is not the case if you overload .ogg to mean
either audio or video, so your argument breaks down there.
Sure, you can give an .ogg file to a DirectShow-based media player
right now, and it'll happily play video and audio (and doesn't care
about what file extension it has). But that's not the point: the point
is that users expect a .mov or .avi to have video in them. I've worked
with plenty of people who've opened up .mov files in QuickTime player
and then become puzzled when they discover there's only an audio track.
This discussion is an issue of user experience ("principle of least
surprise" and all that); not a technical one.
.ogg is already associated with audio even though it can handle video,
and it's confusing enough people that people who use OGM sometimes use
.ogm extensions merely to indicate that they contain video. LIke Zen,
Kenji, and Lourens, I'd suggest the use of a different extension for
Ogg files which contain video. For people who don't care about file
extensions (those who are quite happy with using 'file' to identify
what type of file it is), there's nothing to lose: just throw the file
at your all-in-one media player. For people who do care about file
extensions, this makes a world of difference.
