Hi

I'm running Power DVD 7.3 Ultra on a 3G P4, 2G RAM, nvidia 8500GT with the lastest Forceware drivers in Vista

I have a HVR2200 on order & have been trying to playback the TV3 1080i sample file in Power DVD. Hardware acceleration turns off every time I play the sample clip. I have tried turning on & off deinterlacing in the advance settings to see if that was the problem, but it didn't help. It did the same thing with my 6600GT.

Any ideas? Should it work in Power DVD or will it only work with DVBViewer? Do I need to install nvidia's Purevideo separately or is it part of the forceware driver?

thanks

When you say "the latest" drivers what version are you talking about? I experienced a similair issue rebuilding my PVR on the weekend when I downloaded the latest beta (174 from memory) however moving back to 169 seemed to fix things.

Cool, found the problem

Once I changed the default Video decoder to CybeLink Video with the Vista Media Center Decoder Utility my CPU usage went from 90% (& still dropping frames) to 8-20%
