I know there is another post about this, but that didn't help me. My problem is that going through the process, at the point where it gives you a preview of the dvd, every few seconds the video skips (audio is fine). And when burned onto dvd and played in a stand-alone or PC the video is still skipping. I have updated the codec and my ASPI is fully working, hardware acceleration to full. But still the problem persists.
