I've finally upgraded from onboard ATI graphics to a Geforce 8600GT, but I still can't get DXVA working. I've tried in PowerDVD 8, MPC HC and in GBPVR but I can't for the life of me get it working. Is there a setting somewhere in the nVidia driver that I need to enable, or are all the settings in the decoder. Using recorded .TS files and some mkv files I played with all the settings I can find associated with DXVA and nothing works. In PowerDVD I check the "Use DXVA" checkbox and click ok, but when I go into settings again the checkbox is unchecked. In MPC-HC using the built in decoder the DXVA checkbox is checked but right underneath it it says "Not using DXVA".
Can anyone tell me what I'm doing wrong?
