I recently went in to VideoOnly and was looking at their dvd players. Some are labeled for dvd audio. I was told by an employee that only some dvd players with play dvd audio in true 5.1 I was told that they have separate outs for each channel and a optical or coax can't carry the true discreet signal. This doesn't sound right to me. The price is considerably more for these players and I know that my $160 refurbished 3 year old pioneer off of ebay plays dvd audio no problem. And each channel is discreet through either a coax or optical connection. can someone please clarify, or just tell me that the employee didn't know what they were talking about?
