I'm thinking of buying a new DVD player, and am considering DVD Audio. I have a Marantz HT receiver with 7 channel imputs (I'm assuming this is how DVD Audio is hooked up)? I've heard this is due to copyright concerns? Are DVD Audio players capable of ouputting 7 channels, or only 5 or 6? When playing a DVD Video disk, do you then use the digital connection? And finally is it worth it? When I play DVD Audio disks through my present player, it sounds pretty dood in 5.1. I can't imagine how much better it could get. I would appreciate any feedback from those who know. As you can tell I'm pretty much in the dark.
