Check your video files. Is it truly random, or is it doing it with a  
predetermined filetype? For whatever reason, anytime I play back xvid  
content, via the internal player, or via xine, when I exit the  
program, the frontend will crash. This has been happening for many  
months, and I have the power button workaround found on wilsonet.com  
implemented to restart the frontend whenever it does die.
