I just recently got an HDTV, and set it up with myth. I have an Athlon
2500, 512 Ram, Nvidia 5700 using 7174 on Gentoo. Xv playback works, but my machine
is too slow, and it drops frames. Using 0.18, XvMC plays back smoothly,
except for a horizontal blue line a couple of pixels tall at the top of
the screen.
With CVS from today, the XvMC patch seems to be running as slow as Xv.
I've checked that the libmpeg2 checkbox is disabled, and that XvMC is
enabled. Attached is some of my -v playback log.
