HAVE AN OPTICAL CORD HOOKED IN THE BACK OF MY PS2 AND THE OTHER SIDE ON THE BACK OF THE RECEIVER (ONKYO (HT-S760)) WHEN I PLAY A DVD IT WONT SWITCH TO DD FOR SOME STUPID REASON. I ALREADY TURNED ON THE DIGITAL OUTPUT IN THE PS2 SO I KNOW IT HAS NOTHING TO DO WITH THAT. THE MANUAL SAYS TO GO IN THE AUDIO MODE AMD ACESS THE DD MODE AND THE DTS MODE BUT WHEN I PRESS UP AND DOWN IT ONLY LETS ME GO TO DURABASS AND A DIFEERENT MODE. IT SAYS THAT IT SHOULD IT AUTOMATICALLY TURN ON DD BUT HOW I KNOW IT ISNT WORKING IS BECAUSE THE REAR SPEAKER IN THE BACK IS TURNED ON (THE EXTRA SPEAKER FOR 6.1) AND THE DVD THAT I TRIED IS 5.1 DD YOUR HELP WILL BE MUCH APRECIATED.
