This happened to me with "Chicken Run".  Some DVDs seem to have a
Dolby multi-channel surround-sound track as the default audio, and
mplayer can't handle it.  If you run "mplayer -v ...", you'll see
(among other things) a list of the audio tracks and their
corresponding ids.  Pick one that mplayer understands and specify it
with the "-aid" option.
