I have an HD DVR from Time Warner, its a Scientific Atlantic model. It has no HDMI out, just component video which I'm fine with because programming is 1080i anyway. On the audio side, I'd like to use the optical out instead of the red/white cables it came with standard.
1.) On my Onkyo 607, I'm not sure where to plug in the optical from the DVR. It has inputs but none of them are labeled cable TV in or anything. Where can I plug the optical in so the Onkyo picks it up?
2.) Is there an advantage of moving to the optical versus the red/white cables?
