What does your backend log say when you first start mythbackend? It  
should try to tune to channel 3 at that point. A while ago there was  
a bug that it wouldn't tune to the preset channel so I added a manual  
ivtv command in my startup script to tune to channel 3 and I never  
thought about it again.
