[Carl]

My system appears to be attempting to display the osd behind my video.
Very puzzling.  
I've tried messing with all combinations of playback settings, but
nothing seems to make any difference.

I would be very happy to guinea pig any tests on this feature because I
very badly need it for hdtv playback on my production machine.

I'm using a GeForce 6800GT on my test machine if that's any needed info.
