Some TVs have an optical out that would let you pass 2 chanel or 5.1 from the TV to the Denon with one cable. If you have any HD channels over the air, all you need is a cheap antenna to get full HD and 5.1 sound for TV broadcast. Much better than the RCA cable setup, but only if you like HD over the air and live within 100 miles of a tower.
