hello there, let me start off by saying that it's great to be a new member here. I'm not really new to the HT scene, just a little new to all the new stuff available. Here's my question. On my sherwood receiver, when using the coax input from my cable converter box,a light that says "Digital" appears on the display of the receiver, but when I use the optical input for my DVD player, the same display doesn't appear. Is there a Digital signal coming from the cable box and not from the DVD player? Also, are there any preferences to either connection? Thanks for all the help.
