I knew I could count on you guys. I haven't figured out the conversion thing yet, so I'm using the switching feature. I'm starting to think that heat may be an issue with this problem. I have/had the receiver(s) in a 2 shelf TV stand. The top shelf has the Directv receiver while the bottom shelf has the AVR. I think the combination of the 2 heat creating sources may be causing this. My reason for thinking this is that it doesn't do it immeadiately. It seems to take a few days, slowly, but surely, the picture starts to flicker and eventually disappears altogether. I'm going to move the Denon to a well ventilated stand, next to the TV stand and keep my fingers crossed. Maybe some new cables will be entered into the equation as well.
