I am not sure if I am doing something wrong with my setup? Faulty optical cable? How do I use DTS from my Panaonic Cv51 to my Marantz SR 6200? I have an optical digital cable going from the Cv51 into the Sr 6200 and I am pretty sure I had the cable plugged into Digi-1 and it is selected correctly in the SR 6200 setup menu. I think I had DD working, just not DTS. Any suggestions?
