this is under investigation

I have noticed this too. Has anyone seen similar results on Windows ? 
cause i'm starting to think this may be an endianess issue.

DVD menu's are really hard to work with. Basically if we don't have a 
DVD with an issue it's almost impossible to fix it.
The first issue is a bug.
The second issue is a feature and can be disabled in the dvdnav 
preferences.

This is a crash in the OpenGL module. Since there are numerous problems 
with this module it will be disabled in the final 0.8.0 release (the 
new optimized quartz output is almost as fast).

Also an issue with the OpenGL rendering.

This should be much improved in the 0.8.0 final. You can also nicely 
adapt this in the subtitles options dialog when you open a ogm trough 
the "Open File" dialog.
