If the monitor is in progressive mode the monitor's refresh rate is
60.32 frames per second and the video is 29.97 frames per second.

What is returned during playback? Unless you are using the xrandr
feature in MythTV, it should be the same.

XvMC on nVidia hardware doesn't really work very well. The
chromakey OSD helps a little, so long as you don't use edit
mode or FF/REW or HDTV or timestretch. XvMC is mostly there
for VIA users and for the few people who don't have the CPU
horsepower to do without it.
