[QUOTE="rak, post: 571571, member: 69275"] Hm, I use now latest SVN and I still have stutters, even with 23.976 movies after RR set to 24Hz - so nothing changed for me. It does not show slide show effect as before, but from time to time there is visible stutter without any dropped frames in evr.log. Someone proposed to use AC3 filter instead of ffdshow for passthrough, so I'm going to try this. Anyway if I manually set RR to 24Hz and play the movie in MPC-HC it plays very smooth without any stutter. It looks for me that there is still problem inside MP. Has anyone already found out, why "ERR: Could not get IMFClock interface" appears in evr.log? Can this be related to my stutter problem or can I ignore it? Anyway, I still see the side effect of refresh rate change. When I stop 23.976 movie and the RR returns to 50Hz for the GUI, the menu badly stutters. When this happens, the max FPS is reported to be 37 to 38 only instead of correct 50Hz. Any Idea? Another "bad" effect of the modified RR is that now when the RR is going to be changed, the screen goes black for a second or two, than the GUI appears again for a moment with same RR, than the screen goes black again, the RR changes actually, and after that the movie starts. As this RR change and disappearing/reappearing takes several seconds, it looks like the movie will not start and I tend to press play/stop again. [/QUOTE]
