Harmon Kardon AVR 7300. Currently I have my sat. dish, HK DVD player and Xbox 360 hooked up through my HK via component video. I have a few other components (Tivo for media server and outdoor video camera) that I would like to add to a few of the regular RCA inputs but I have an issue. When I hook anything up to the regular RCA inputs, they don't work. I'm wondering if you can't use both component and RCA at the same time on this flagship receiver? And yes, I am using different input numbers. Right now I'm using 1, 2 and DVD for the component setup. I tried using 4 for the tivo\camera but it doesn't seem to work. What's really strange to me is this...with or without the xbox\camera plugged into the receiver, if I choose input 4, I get the display from input 2. This is true of all other not currently hooked up inputs. They all display video from input 2. Does anyone have any ideas?
