For what it's worth, I am having similar problems. I thought it might be me or my setup, but after reading this thread it seems this is a known problem. I have an NVidia FX5700LE with the 6629 drivers. Linux Kernel 2.6.10 from ATrpms. My CPU is a EPIA-M Nehemia 1Ghz. Compiled Myth-CVS as of 2/6/2005 I just purchased the NVidia card a week ago because my onboard VIA-Unichrome [driver] could not output the HDTV 1280x720, 1920x1080i modes... Currently I have the XVMC options enabled, but no OPENGL for sync. By the way, should I enable the OpenGL sync code? Is that supposed to be better / less overhead? I saw on the ATRPMS discussion that OpenGL sync was causing high CPU load for some people... I get the prebuffering pause error messages when trying to watch LiveTV. On 1 out of 4 attempts to watch LiveTV, it works okay (no prebuffering pauses). However, the other attempts I get video freeze and the prebuffering pauses in the logs. I have tried turning off XvMC, but since my processor is only 1Ghz, the CPU load runs close to 100% during playback resulting in a jittery playback. Using libmpeg2 did not seem to improve playback. Was that supposed to be more CPU efficient? I also get the jumpy blocky ghosting as previously described. It seems to get much better when I turn on Bob-Deinterlace with XvMC enabled. But then I have the freezing problems. I have not had any problems with DVD/ISO playback via Xine using XvMC. I would love to help fix this problem... I am not familiar with the code. If someone could point me in the right direction (files/ fix ideas?), perhaps I could give it a shot. --Dave
