crash with one DVD

Hi,

I have one "custom" (read made with iMovie) DVD which is causing
libdvdread (as well as libdvdnav, since they use your code) to crash.

Backtrace when using ifo_dump /mnt/cdrom2 0 is :

Starting
program: /mnt/gnome/cvs/libdvdread-0.9.4/src/.libs/ifo_dump /mnt/cdrom2
0
libdvdread: Encrypted DVD support unavailable.
libdvdread: Attempting to use device /dev/hdc mounted on /mnt/cdrom2 for
CSS authentication

My PS2 is able to read this DVD without crashing (but it isn't able to
activate optical output for it, so there might be other problem with
it..). It starts directly by playing the film.

If you need more info, just ask..
