I think that opengl_vsync is an issue if you actually tick the box.
I'll check my FE and let you know what options I have enabled there.
Who knows, maybe you've got something checked that is messing other
things up.  If I recall, I've only got XvMC and BOB deint turned on.
Nothing else.  As I said, I'll confirm that.

I think I saw you were going to go back to FC5.  Have you done this?
Not to state the obvious again: make sure the nvidia module is loaded,
make sure xorg is using the nvidia module.  I recall you had 2
monitors/TVs hooked up to this card.  Have you tried launching myth on
the other monitor/tv?  Just trying to see if this might be the card.
Forgive me if you've posted this: are you using mirrored desktops on
your video card for the 2 monitors/TVs?
