[QUOTE="hirscho, post: 294542, member: 28029"] Well it seems that you guys have more difficult problems than me, so maybe I can help. If the TV or video does not freeze at the beginning of an HD stream there is no stuttering at all and the picture quality is brilliant. I had to play a little bit with drivers and codecs. 1) I use the nvidia beta driver v177.79. It is stabil and the first version where you can also change the video chroma output level to PC scale (0-255), so that you can enjoy TV black levels as they are designed for. 2) With coreAVC I also get a black picture playing HDTV videos. On my system coreAVC has also problems with interlaced materials. If I use the cyberlink codecs for mpeg and h.264 streams the picture is great and the hardware deinterlacing is perfect. Please be sure to check the DXVA option in MPs setup. When playing an h.264 video (1920x1080) the cpu utilization never raises higher than 25% even my graphic card is not able to support any hardware accelaration on h.264 streams. 3) Be sure to use the exclusive mode for VMR9 unless you don't use EVR.
