Your processor talks SSE, the problem you have might be related to 
desktop-effects and settings for mythtv. Ubuntu mythtv isn't updated 
very often and if it is, I usually need to adjust some setting to get it 
working again.
OpenGL is used for some shiny effects when changing menus amongst others 
and should work with a Nvidia card.
The probleem you have seems(very little information to go on ;)) to be 
related to X. Maybe some more info on the logs of X and mythbackend help 
and start mythfrontend from a terminal, that way you can see the error 
which causes it to quit.
