I don't understand why my denon 3802 stopped decoding DTS signals from my computer and dvd player. It used to be that whenever i pop in Gladiator, either the DD or DTS light was red. Now neither lights go red and whenever i switch to DTS there would be no sound. Dobly Digital still plays fine though but without the light. I reset the microprocessor to see if the lights burned out or maybe i messed up some settings. Both lights were fine but they still wouldn't light up when i play DVD's nor do i get any sound when i switch to DTS. I then thought that maybe the culprit was the flimsy optical cable that i have. So i grabbed a digital coax cable but i still get the same problems. What's going on??? HELP!!!
