I see the same thing with the standard NV driver as well as the NVIDIA binary driver. I still get good playback in both even though the CPU is 4 times greater, but I am also running on machines that are over 2Ghz. I honestly think that there is something in the memcpy or scheduler code that is different under the respective kernels, I just haven't been able to get anyone to acknowledge that there is a difference that could produce this "wasteful" behavior. I have reported the issue to Xfree, Nvidia and Xine and haven't received any real feedback. Xfree says to use 4.4, but 4.4 didn't help. I just think its kind of silly that if I want to move to a new kernel that I have to waste CPU when doing the same things as before on the older versions; MS has been doing this for years, I would hope not to see the same thing from linux. If this is by design, that would be acceptable, since 2.6 certainly seems more responsive than 2.4, I just wish that someone would acknowledge the fact.
