Nvidia + ATI in one box = No PowerDVD?

[LxMxFxD4]

Any ideas?

PowerDVD 10 (trial) loads but when I go to play ANY video file, dvd or blu-ray it crashes.

I have both an Nvidia 8800GT and I brand new ATI 5750 in my comp. Would this cause conflict?

CCC: 10.4
Nvidia: 197.45

Appears disabling Nvidia card in device manager solves the issue. May have to do this everytime I watch a dvd or blu-ray?

Any other solutions ?
