>From the mplayer-dvb mail list, this problem has also been reported by another
individual.  He mentioned in his report that lavc was working with mpegpes in
the mplayer-pre7 release.  From my testing, this was working several weeks ago
in the head mplayer cvs branch, but I can not be sure which cvs date is was.
So, I grabbed a copy of the mplayer-pre7 release and built it with a copy of
ffmpeg cvs from 2005-04-27 and ran into the same error.  Therefore, I think it
has to do with ffmpeg, but I cant be certain.

Im mainly trying to narrow down the time it stopped working. Normally, something
like this *should* work (or used to):

mplayer test.avi -vo mpegpes -vf expand=544:480
