Hi. I just bought the Denon AVR-2106 amplifier/receiver. I'm going to attach my VCR and DVD player through it to my TV (coming in a couple days :-) ). What exactly is digital coaxial cable, and how much should I spend to get it? I need two cables, each 6 to 10 feet in length. Is it just regular RCA cable, or is there something really to it? I am under the impression that I need either digital coaxial cable or optical cable to achieve 5.1 sound from my DVD player (since it doesn't have a decoder built in). Am I right, or is there something I am missing? Also (stupid question, but...) digital coaxial and optical output only send audio signal, right? I still need to send over component video, right?
Thanks.
