[FFmpeg-user] some files unplayable in WMP

Are "not playable in WMP" errors worth reporting?

Example:
$ ffmpeg -i sintel.mpg -vcodec copy -acodec copy out.avi

produces a file that has working audio but not working video in WMP
(sintel.mpg itself plays fine, out.avi plays fine in VLC).

$ ffmpeg -i sintel.mpg -vcodec copy -acodec copy out.mpg

produces a file that has working video but no audio in WMP (and also
no audio in other players, see my next post).
Cheers!
