Its actually been doing it ever since I bought it. I should of took it in while under warranty but it never worked out. I think the 906 is upconverting the signal,how do you set it up to just pass through. I am using HDMI cables. I've tried lots of different hdmi cables it doen't seem to make a difference.
You can tell when its going to get a signal when cycling on and off when the big onkyo text pops up on the TV screen. when you get a signal on one source you will get it on all sources.
Thanx
