I am looking for my first receiver to start my surround sound system but I have no idea how everything will connect once I get the equipment. I already have the TV, VCR and DVD player, but I need to know how many inputs & outputs to look for in a reciever. My TV has S-Video and Component Video Inputs. My DVD player has S-Video and Component Video Outputs, and digital audio outputs (optical and coaxial). My VCR is a few years old...I assume it just has basic connections. I also need to hook up the speakers when I get them, and a digital cable box. The only other thing I forsee myself adding in the future would be a TIVO, but I'm not sure if that would connect to the receiver. So, what kinds of inputs and outputs, and the minimum quantity of each, should I look for in a receiver?
