I don't know too much about this stuff, so maybe someone can give me a hand. I just bought a Sony STR-DE995 receiver (7.1 w/ DTS and all that jazz). On my old receiver I just ran a optical cable from my DVD player to my receiver to get 5.1 Dolby Digital sound. I tried to run my optical cable into my new receiver, but there was no specific optical input for DVD players (just TV, MD sumthin' or other, and CD/SACD). There is an input for a digital coaxial cable for a DVD player on the new receiver. The optical cable gives me sound from my DVD player in the other inputs, but only of the basic Dolby Digital variety. To get DTS, do I HAVE to buy a digital coaxial cable or is there some way I can get DTS by running the old optical cable into one of those other selections. Is there any chance I am just not setting it up on the receiver the right way?
