[QUOTE="dm15644, post: 102074"] Hi Taipan, good to hear that maybe I don't have to spend any money! To answer your questions: Yes, I get the stutter also on TV. The refresh rate of the beamer is that to 50Hz, the maximum fps in the settings context is set to 100. About VGA I cannot say since I have no VGA cable at hand to check. However I have an S-Video connection in place, and the fault is present there as well. About PCI latency: I've read the post about changing the latency, however I'm not sure what to change here and I'm a bit concerned about screwing up my system. It is also strange that I don't have a setting for the primary Radeon 9950 adapter, just the secondary. See attached screenshot. Can you recommend settings to try? fyi, in the meantime I've also checked the readings when pressing "!" during playback. When stutter occurs, the "sync" and "jitter" figures go up. Maybe this helps. Cheers! jayrock [/QUOTE]
