I am having a very hard time getting smooth playback of HD Video on this mobo running as an MD. I have 512 MB shared DD2 800Mhz to the video card. The processor spikes up when playing 1080p or even 720p video, I tried various different encoding, but xine player spikes up the CPU usage and the video playback is not pretty. Any ideas on what can be done? I understand that xine doesn't use vdpau?
