I haven't messed with this at all aside from XvmcUsesTextures false  
since I had a hard time getting the res I needed and all that. Once  
it worked, I new enough to leave it as it. I might have added  
ConnectedMonitor TV, as well.I don't remember. Someone also mentioned  
not being able to get 800x600 on their S-video out. I'm able to do it  
with these settings.
