I have a Toshiba 2710 DVD and a Marantz 5200 (no problems), and I have a couple of DTS related questions. When a DVD has DTS, I like to listen to that audio choice. I make the correct choice on the DVD, and then select DTS on my receiver. There has never been any problems with the movie it self, but the openings sometimes have no sound...the THX thing, and some other opening info does not have any sound. Also when playing the extras, I have to switch the receiver off of DTS. Am I doing something wrong?
