This DVD doesn't play

The DVD is Phantom of Inferno, which is an interactive DVD game that plays
on DVD players, using menus in strange ways.  It plays video clips and still
scenes along with subtitles; occasionally the user can choose an option and
it will branch to one of several results.

I've tried it on Xine and it actually lost sync between the still images and
the audio.  Ogle works better, but I get subtitles that appear on top of
other subtitles.  The DVD plays fine on a Playstation 2 (as a DVD, not as a
PS2 game).

Note that my picture and sound are fine, and I'm not having any decryption
trouble.  The problem is with the subtitles.

Also, when I start the DVD I get a warning that the game might not play on my
DVD player--and another screen overlaid top of it.  It looks to me as if the
other screen is made of subtitles and the game is expecting that on a working
DVD player it should cover up the warning.

Versions are new: Ogle 0.9.2, libdvdread 0.9.7.  OS is Mandrake 10.1.
