Hi, Lookin at buying a new DVD player, entry level. I've seen a few with a 6 channel (5.1)output on the rear panel (6 RCA's) in addition to the ususal digital Coax and Optical. These DVD players are NOT DVD Audio players. My HK 310 receiver has a seperate 6 channel input. What would be the advantage to this setup if its not an actual DVD audio player? How would this be better than just using the one Caox for my 5.1 discs? Why have both and how can I use it? Also, what kind of cables would I use? Simple RCA style? Thanks, Confused.
