This should be an easy question for someone who knows his stuff. I have a fairly bog standard DVD home cinema system a Panasonic SA-DM3. The thing is, I don't know if its working correctly. As I understand it most DVD's are presented in DTS. I have icons on the front of the player that light up when the disc comes on. One for surround, one for pro-logic and one for DTS. Both the others light up but never has the DTS icon lit. How do I know if my player is playing the movies in DTS????
