Did anyone ever find it useful to change a process priority? I never did. When I encode full HD video in Encore, it takes a lot of CPU power and even if I watch an HD movie on KMplayer, it has a little stutter. I tried lowering the Encore process priority and I also tried raising the KMplayer's process priority and I also tried un-checking some CPU's in the Encore process Affinity but it had no effect what so ever. Is this ability to change process priority real or what? Is there any other way to change Encore's process priority? I don't care if the Encore encoding takes longer, as long as I can do other things with the computer and have Encore use less processors or\and less CPU power. Thanks.
