[QUOTE="Scythe42, post: 571052, member: 95833"] I did some more test. It seems a similar problem is still there when you first play a 23.976fps file after MP started. After that, all 50i/60i/25p playbacks show some micro stutters. Not the same as before. It's very bad with PDVD9. Other filter behave better here. Alt-Tab does not solve this. It's persistent as long as MP runs. If the first thing you play is 50i/60i/25p the problem never occurs and playback stays smooth. At least I cannot reproduce it in this case. Very strange problem. There are other annoyances we stumbled across when working on smoother playback and sorted them out as good as possible. Maybe an additional workaround is needed for this different scenario. But I think the truth here is that changing the refresh rate during an application is not fully supported by Microsoft and it's probably not 100% fixable for MP1 with the current Windows patch level.
