I'm happy with just the DVD, I don't watch much TV only the news and a DVD now and then. I rather drink beer and look at the stars.
The HDMI from the Concertone/Genesis is required to get HD VIDEO from the DVD player to the TV (otherwise you get standard -crappy- video). The Surround sound comes right from the DVD, through the radio to the speakers and the TV is not involved at all except to show the video (you can even mute the TV because the radio is handling the surround sound).
The issue being discussed here, is if there is an over the air or cable channel or show being broadcast in surround sound (like the Simpsons). In this case, the TV is the origin of the audio (and not the radio). To get that digital audio to the radio (so you get the surround signals), you must use a digital connection.
Some TV's (like mine) do not have a digital output (so I need to do like you do and use the analog stereo L/R RCA (white/red) audio connection from the TV to the radio. This will get you your 5 speakers working, but it will not be surround sound, just the same L/R channels from 2 left and 2 right speakers with a mixed center channel and some lower frequencies routed to your subwoofer.
ACK! This is what I get when I "reply" from an email link. Camaraderie covered it very well. My apologies. Herk
