Should XvMC based decoding be equivelent to xv? On my machine (running MythTV) whenever I enable XvMC it makes the video quality look blocky and crappy. This is for playing DVD's or watching analog TV from the PVR-250's. The video is being scaled up to 1024x768. HDTV video looks good using XvMC and the machine is not fast enough to play with the Xv driver.
One note: I am not able to use XvMC when AGP is enabled. Any application using it locks up. I have to set Option "NvAGP" "0" (disable AGP) to get XvMC to work. Should I return the 6200 and pick up a 5200 instead?
