Please take a minute to help a newbie understand. I have gathered that the "types" of connections increase in quality from composite to S-Video to component. But I don't know how that translates to passing HD signals. Also, I am not sure the trade-offs between signal quality with DVD to HDTV versus DVD to Receiver for component switching. As you can see below, most of my "stuff" is not here yet. Please recommend connections (to/from) and cable type (digital, optical, component, s-video, etc.) Here's my equipment: Harman/Kardon AVR320 (arriving tomorrow) Toshiba DVD player (non-progressive scan) Sony 5-disc cd player Sony KP57HW40 (on the way) Hughes DirecTV HD Receiver (on the way) Tivo (on the way) Thanks in advance!
