what is mpv?
with this:
C:\libav-win32-20131121\usr\bin\avconv.exe  -i sintel.mpg -c copy
sintel.avconv.mpg

mplayer is able to play video, but no audio.

if it's sintel.2.5.mpg it was a rip from a DVD.  Mencoder possibly, or
mplayer -dumpstream.

Thanks for your help in this.  According to the discussion on the
trac, the problem may be that it uses this muxer:
MPEG sequence, v1, system multiplex

which most players don't expect to have any advanced things in it?
thank you.
