Gah, I'm pretty sure I've updated xorg-x11 since initially installing the 
nvidia driver. I re-ran the nvidia installer, rebuilt Myth with OpenGL sync 
enabled, and now it plays nice. (smacks forehead). I had one little oddity, 
in that HD programming was only visible in the upper left quarter of the 
screen (xrandr'ing from 960x540p to 1920x1080i), and wouldn't clear up even 
w/reloading X. A reboot cleared the problem though.

I haven't seen a noticeable difference between OpenGL and RTC yet, but I 
haven't watched a whole lot just yet, mostly been trying to figure out the 
ABC issue.
