English subtitles don't work with a korean DVD

[datpeter@…]

There's a bug with a special korean DVD (the movie named 'Old Boy' won The Price
of the Jury in Cannes 2004). Korean subtitles work perfectly while english are
not shown. As xine showed the same effect, I thought the bug was provoked by
libdvdread3. To check this, I started the movie in ogle and it showed to work.
I'm aware of the problems to debug this, not having this very DVD, but I can
offer help in any form, like starting a gdb when you tell me where I am to set
the breakpoint :-)

Never ever do that! Please post the full output of mplayer with -v. You can add
it as attachment if you think it would take up too much space...

Not enough information available and DVD subtitle selection was fixed somewhen
in the past, so it may work with latest MPlayer version.
