Documentation says that aspect ratio can be stored in mpeg4-inside-avi
files, but only mplayer will understand it (although I don't think it's
a problem to add this to windows players, if you mail their authors).
But that's enough for me.

Bad thing is mplayer can set this option only when encoding video with
lavc. But I think there should be other way, and wanted to know it...

I've got several videos with wrong aspect ratio... I don't like to start
it, remember that it's wrong, and restart mplayer manually setting
-aspect each time.
