This sounds like an issue with Mesa OpenGL. If:
makes it work (when configured with the OpenGL theme painter), then it
means you don't have the nvidia proprietary drivers installed properly.

That's a known issue that's being worked on.

I did both PVR-350 TV out and nvidia TV out, and I found that with
PVR-350 TV out you either got nothing, or you got the best-quality
output you could get from a PVR-350 TV.
With nvidia TV out, you could get any number of quality levels depending
on how you had configured everything (Myth, X, nvidia drivers).
Therefore, people who didn't take the time to figure out exactly what
setup to use often claimed that the PVR-350 TV out was superior. IME,
though, once properly configured, the nvidia TV out quality was just as
good as the PVR-350 TV--the weak link in the chain at the end of my
configuring was NTSC.
For instance, don't be led to believe that 720x480 or 640x480 will give
you the best quality picture with nvidia TV out.
Anyway, just my opinion.
