Guys, I need your help on something I know nothing about. My good buddy has a B-day on Saturday and we want to get him a DVD player. A local B&M shop has a Sony that has a DD and DTS decoder built into the DVD player. He has a Yammy RXV-850 which is only Pro-logic. My question is:will he get full DD & DTS when he hooks up the DVD player to the Yammy, or does he need a new receiver to go digital. Thanks in advance for any help.
