[QUOTE="kkendall, post: 361155, member: 49885"] Unfortunately I have sort of the same problem. Some 720p stutter here too. Some play fine though. And as far as I have seen it also sometimes happens to 1080p files. All are 24p material x264.mkv movies. Have you tried hitting [Control]+1 (or [Shift]+1, I can't remember)? It will show you the framerate. I noticed that the stuttering is caused because the framerate that is supposed to stay at a constant 24fps, becomes variable... It sometimes drops to 10/12 fps!! My pc should be able to handle all HD material flawlessly, it's powerfull enough to decode it, even without hw.acc.. So I probeably have the exact same problems you have, the only difference is I use SPDIF to output my audio and use the PowerDVD8 codec for x264 content. EVR is always on here too. I haven't tried to check what happens with graphstudio, but I thought the info could already be usefull. I'll try graphstudio when I have the chance. Have the devs a clue what it could be and are they looking at it or is this something that has not yet been picked up? [/QUOTE]
