I hooked up my newly purchased Panasonic dvd-s35 to my Pioneer vsx-d608 dolby digital/dts receiver. I used an optical cable and connected it to the second optical input. The first input is already connected to my direct tv satellite receiver. When I switched the receiver to dvd/ld and played a dvd (Band of Brothers) I had a beautiful picture but no sound. My receiver display said that my audio was analog, and not digital as it should have been. I pressed signal select on the front of my receiver and the display changed from dvd/ld to dvd 5.1 channel however it still displayed the audio signal as analog and I got no sound. I had to connect rca cords to the dvd/ld connections on my receiver to get sound and then it was only stereo. I have gone into the menu for my dvd setup and made sure that it was set up correctly for dolby digital which is the default setting anyway. I have also tried connecting the optical cable to the other two optical inputs on my receiver, still no sound and the display shows as an analog signal being received. I get great dolby digital sound from my direct tv and it displays correctly on my receiver display as being a digital signal when I'm watching an HBO movie in dolby digital. I just cannot get my receiver to recognize the signal from the dvd player as digital. Naturally I don't have my instruction manual for my receiver anymore, its an early dolby digital model. Does anyone have any suggestions, I know its not my cable I have tried them both, both work for tv/sat but not for the dvd.
