I am running the RC and have recently started having problems with video rendering being very poor, either very jittery or a very low fps or the video just stops rendering but keeps playing then it comes back and plays about 10 seconds fine then it does it again. I have the latest video drivers and it does it on every player I have, VLC, WMP and I also tried WMP Classic. I installed a codec pack just in case but it didn't make any difference, I am using a sound card other than the built in one on the motherboard because I didn't like the software for it, didn't think that would affect it though? it worked fine on it for a while. Also, I run XP on dual boot and video is fine on that.
