Are you using one of these newer nVidia cards with VDR/softdevice?  Would
you share your settings and experiences with it?  Using the psuedo setting
for OSD I would get blinking video.  Using the "software" setting I would
get OSD but the colors were wrong during DVD playback.

Yes video textures through OpenGL is a wonderful idea, but what in VDR
land supports that?  Softdevice (according to another list member) doesn't
support XvMC so I assume it falls back on overlay support for OSD.
