[QUOTE="dm15644, post: 103030"] Still not solved, unfortunately..... With movies and DVD I still get problems. Every few minutes I get stutter, then the "jitter" values jump by say 20. But, no frames drop. It's like the video stops for a moment and then catches up again with audio. I briefly checkd the omega drivers, no improvement. With Powerstrip I made bas experiences earlier, therefore I'm a bit reluctant to test it. DPCLAT also didn't reveal any news, the PCI latency is around 70 us. I've checked for unusual events for about an hour, but the maximum was 1400 us only while running MP. Pretty high though.... I've tried to disable Ethernet, unused devides, etc, but no success. I have also tested Reclock which also didn't help. I starting to abandon the idea that it is a sync problem. The "!" jitter figure, does that indicate the data is not reaching the video card in time? Any more ideas how I can figure out the cause for this? Thank you very much for your help /jayrock [/QUOTE]
