Red herring? So the mpeg4 stuff is in there but not used?

Xv is running, im using the nvidia driver and its 6629. glgears is giving 
me like 2400 fps.
I tried XVMC which ran much better (45% CPU) for about 5 seconds  but then 
myth started to complain about loss of video buffers and stopped 
displaying video.

Im going to try to use the kernels agpgart when i get home.

Red herring.  Not needed.  Ignore it.

Double check that Xv is running properly (use 'xvinfo').  You're using 
the 'nvidia' driver, not 'nv', right?  What version?
