I have yet to get xvmc to work, but really need to since my machine is 
getting taxed on 1080i HD playback that has to be downscaled to 1280x1024 
(thats as high as my LCD goes).

You may wish to verify that your DISPLAY
environment variable does not use an external
network connection.


Every time I try XvMC, these are the exact same things that happen. I'm 
currently on the latest drivers available on the ~amd64 tree on gentoo, 
which happen to be 7174. I am also on xorg 6.8.2-r1. I have read a little 
bit about needing an /etc/X11/XvMConfig file or so, but no such file exists 
(at least on my system). Also, opengl does work fine for this card as an 
opengl sync for myth or for video games.

My Related hardware:
Athlon64 3200+
Asus 68V SE Deluxe
Pny Nvidia 6600GT
Gentoo Linux 2005.0 ~amd64

I do run myth cvs usually, but I have tried 18.1 as well.

This problem isn't myth related because I can reproduce similar problems 
with mplayer when trying xvmc.

What could I do to fix it?
