I've been living with this problem for a while on my Mac Mini (intel  
CPU) running Ubuntu, as well. All of my content is 720p. Sometimes  
killing MythFrontend was enough, but sometimes I had to kill the whole  
x-session in order to get anything to play back afterwards. On a whim  
last night, I changed the resolution of my display to native 720p and  
I haven't crashed at all so in my case it looks like stretching  
content was the culprit.
