[QUOTE="ziphnor, post: 82105, member: 14215"] I am not using any post processing. I tried PowerDVD 6 instead. Using 'Cyberlink Video SP Decoder' with hw accel in MP i get 30-40% CPU usage, but here is the thing, its still very jerky. (that is the correct cyberlink codec , right? There is another called Cyberlink MPEG Muxer). If i disable hw accel i get up to 85% cpu usage buts its smooth/working as it should. I tested again with Intervideo codec and hw accel on, it gives me ~100% CPU usage and terrible stutter as before. The Cyberlink codec is better, but its only smooth without hw accel. I havent tried playing back HD in PowerDVD 6 itself, because unlike v.7 it doesnt support DVR-MS playback(and the Compress option in MP doesnt seem to like HD files). Diagnostic/solution ideas are welcome :) If i disable hw accel i get 70-85% CPU usage but then it plays smooth. [/QUOTE]
