Either component with separate sound, or HDMI which includes sound. Component is analog and HDMI is digital. I've never been a fan of running my digital video (HDMI) through a receiver. Too many devices to turn on to watch TV. I run my HDTV (satellite) directly to my Sony SXRD and my digital sound directly to my Denon receiver. If I just want to watch TV I don't have to turn on my receiver. If I want surround sound I then turn on the receiver.
