It's probably time to start playing with your TV Playback options.  
Turn off any deinterlacer you have running to see if that helps. Turn  
on aggressive audio buffering and check again. Also, can you tell if  
you have OpenGL working correctly? Oh, one more thing to check in your  
xorg.conf:     Load "glx" in the modules section. I think that's the  
option that made my system go from "completely unusable" to "Hooray it  
works perfectly".
