I must be doing something else wrong.... I removed the old nvidia 
drivers "nvidia-installer --uninstall", installed 7676, rebuilt mythtv 
again against this version and bam... Nothing changes. I can't enable 
OpenGL-Vsync no matter what, and I can't have XvMC run without eating 
all of the CPU with OpenGL-Vsync on or off. In fact, I can't even turn 
off vsync.

Its just the same message every time even if I
update settings set data = 0 where value = 'UseOpenGLVSync' and hostname 
= 'mythtv'; (BTW, I had to manually add that record since I didn't have it)

nVidiaVideoSync: VBlank ioctl did not work, unimplemented in this driver?
2006-02-07 21:02:19.331 DRMVideoSync: Could not open device 
/dev/dri/card0, No such file or directory
2006-02-07 21:02:19.331 RTCVideoSync: Could not set RTC frequency, 
Permission denied.
2006-02-07 21:02:19.332 Using video as timebase
2006-02-07 21:02:19.333 Video timing method: USleep with busy wait

Am I supposed to be using SVN for this stuff or something? I don't have 
this mythical enable/disable OpenGLVsync button that people speak of and 
I'm on 0.18.1. I thought they were saying that the new myth was going to 
be out last week or something but I guess that was just say-say because 
I havn't seen it.

If it means anything, my card is a ti4600.
