After looking around, many of you are much more hard core than I am... WOW

Anyway, I just got the 970 all fired up and running, connected my Poineer CLD-D604 via coaxial cable from the RF output, popped in a AC-3 disc (Aliens btw), and got no sound. It defaulted to "stereo".

I have an optical output on the LD as well, I just don't have a cable. Is that the way to get this to work?

Oh and this unit rock so far, but I was using a Adcom GTP-600 before (no DD or DTS)

Thanks!
