Hi, i've just purchased a new mobo for my HTPC (Asus M3N78) which uses the new GeForce 8200 chipset which supports hardware decoding for blu-ray discs. Anyway I built up my PC Windows Vista 32, all the latest drivers installed (Nvidia 175.16), My CPU is an AMD 64 X2 BE-2350 and 2gig of RAM installed. Installed and updated PowerDVD 7.3 and BluRay is unwatchable pausing and skipping everywhere, CPU is almost maxed at 90%+ I checked powerDVD settings and Hardware acceleration is ticked. I then put my old ATI 2400 graphics card in the same machine installed the ATI drivers and tried the same movie again, this time the movie played perfectly with the CPU steady at around 40% Has anyone else got a 8200 mobo and can get satisfactory playback of BluRay discs with minimal CPU usage? Any ideas where i'm going wrong on my install? any help is much appreciated.
