I have installed an nvidia driver with vpdau support, patched xine-lib1.2 with the vpdau patch, and recompiled xine-ui
I have improvement with HD channels cpu utilization wise but still choppy image.
Do I need to patch vdr itself or change some config options to optimize the speed?
nvidia 8200 on-board

only Speedup patch for VDR-1.7.5 from Reinhard Nissl - see in vdr list

Don't let the powernowd or the cpufreqd clock down your CPU. With the current Nvidia-Driver you need at least 2GHz clock speed with your AMD CPU. The onboard graphic needs the memory controller inside the cpu to access the memory and it seem it is not fast enough if the CPU is clocked down. For less power consumption you could undervolt your CPU instead.
More Informations you can get in the http://vdr-portal.de. VDPAU is a hot topic there.

This is not correct. I am having problems with droped frames on atsc hd and I turned off speed scaling so both cores would stay at 2.6ghz. It had NO EFFECT.
