Well, I have checked the same DVD plays ok under WinXP with PowerDVD and
on a set top DVD player, showing the language names without problems. So
it definitely looks like this is a problem with mplayer. The version was
the one from debian testing:
MPlayer 1.0pre7-3.3.5 (C) 2000-2005 MPlayer Team
Just to let you know. Best regards.
