Hi folks, still messing with my new processor however on reading this forum on dts it states that galdiator is very good on dts, i put the dvd into my yamaha 530 selected dts in the dvd menu and my amp is set on dvd (auto). When the film started to play the amp display showed dolby digital...hummm .... so I switched it on the remote to dts so the display light came on and i got no sound what so ever. Back on the dvd menu I selected 5.1 and put the amp back to auto and on came dolby digital and the sound. any ideas what I have done wrong with dts?
