I had the exact same problem with my setup running a Geforce MX440 card. I added the following to my "Device" section in /etc/X11/xorg.conf;
Option "XvmcUsesTextures" "true" Double check you're using accelerated nvidia drivers, and make sure your xmvclibs are up to date. Works like a champ for me, though a little flaky on my motherboard due to what I suspect are DMA problems (will report back on that after an upcoming mobo upgrade) Hope this helps! ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mario Limonciello Sent: Saturday, May 21, 2005 7:51 AM To: Discussion about mythtv Subject: [mythtv-users] XvMC output not working 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?
