I'm utterly baffled by this but I'm sure the fix must be simple - I can play DVDs fine on my ubuntu machine but I have just bought a new DVD and there is no sound.
The sound works on all other DVDs I've played and normal avi files also work, music works fine. So I think it must be a coded missing but I have no idea how to narrow it down. Can someone help?
For reference I have libdvdcss2, libdvdnav4, restricted-extras installed. I have tried vlc, mplayer and parole with no success.
Any help to determine the missing codec would be really appreciated.
Example mplayer output for working DVD:
Playing dvd://.

Maybe you are playing a non-interleaved stream/file or the codec failed?
For AVI files, try to force non-interleaved mode with the -ni option.
