I just purchased a samsung 931 and a Samsung DLP TV. I am not sure if I have my connections correct on my receiver. I have an Onkyo receiver. I connected the DVI from 931 to TV. I connected the Optic cable from DVD to receiver, but I only get Dolby Digital to show up on my receiver. Before my receiver would switch to DTS when applicable. If I switch it to DTS the sound goes out. Is there something else I need to do? What is the best sound quality as far as DTS THX Dolby Digital .... Thanks.
