Please help a newbie with a stupid question: Where do I connect the cables to the AVR 300 from a U.S. digital cable box (Time Warner)? The manual doesn't clearly illustrate this, and the Internet-based diagrams from Monster show a receiver with connections to a "digital audio in" and a "TV/Mon input", which I cannot readily identify in the AVR300 manual. I've got the connections for my DVD and plasma TV figured out--it's just the cable box that's got me stymied. I know it's stupid, but I really appreciate the help from you who have long ago gone through this. Thanks.
