I see the RCA type of cables on the back of the HK for the analog hook up for 5.1- 7.1. However, I have never seen this many outs on the back of a DVD player (I haven't gotten the sony yet, xmass present). Are they common on DVD players? I was curious until you responded to my posts what they were used for on the receiver, since I had never seen a DVD with those amount of outs to match the ins on the receiver.
