I have not been using the DTS function because basically it didn't work. I was still getting used to everything else in Surround Sound. One thing at a time. Tonight I was actually reading instructions and saw that my Sony NS700P was not set up correctly so I pressed all the correct buttons and still nothing. Then upon further reading I spotted something that brings up a question. I need a one plug (1 each side) coaxial digital cord that runs from the Player (Digital out) to the Digital Input jack on the reciever. This I do not have. Questions 1. is this a SPECIAL coax cord that I will have to buy? 2. What does this cord do anyway????? 3. Is this the missing link to my DTS problems?
