Sounds like the issue I'm having currently.

I had issues with 720p at 1080i, but since my TV is native 1080i I'll
try turning that off once I get the rest figured out.

I'll have to play around and find *my* magical setting, at least I
have an idea of what to try turning on and off...
do I have to restart mythfrontend if I make changes to any of its
OpenGL settings or if with nvidia-settings options?

thanks!
