I gave up on the 5200FX card and threw down $200 on a GeForce 7600GS  
card. Problem 1 is solved since I now have a Dual-Link DVI port to  
support the full 1080p resolution.

Still have this issue with the new card. I turned off OpenGL  
transitions and the images display fine.

Done with the help of http://losdos.dyndns.org:8080/public/mythtv-

Still the same issue.

Is there an issue with OpenGL and the nvidia drivers (I'm using 8726)  
or is there an issue with running OpenGL at all at 1080p resolution?
