[mythtv-users] Nvidia quarks, please explain.

[Chad]

Hello, just reading over a plethora of threads that contradict each
other.  It seems that some people can play back HD content via XvMC
and get away with having a 1Ghz processor.  Others claim that with a
much higher CPU, nearing 2Ghz, even with XvMC enabled they are max'd
out on their CPU and nearing crashing their system.

So, I am wondering what these quarks are, and if they are fixed in
certain releases of nvidia drivers, and most importantly, does XvMC
really take that much load off the processor?

Thanks!
