Make sure that the digital audio cable from the DVD player is properly connected to the unit, then step through the Onkyo menus and ensure that the digital connection you used for the DVD player is properly associated with the DVD player's video input.

Hello ,unfortunately the answer is yes,in order to get dolby digital or dts audio either an optical,coax or hdmi cable is required as these are the only methods of digital audio transmission.However the dvd player should have analog outs (red and white jacks) if you would be satisfied with dolby pro logic than you can still connect using these cables to your existing equipment.
If you are playing media that has both dolby digital audio and dts audio, your player and your receiver will decode the first audio codec listed first by default unless you select it otherwise yourself. If your remote or receiver has an A.F.D. (auto format decode) button, press it until your display shows that the sound source is dolby digital or DTS, whichever sound mode it was you wanted when you started your DVD.
PCM is standard when using HDMI cables, you are passing an already decoded audio signal to the receiver and it outputs the sound and does nothing more. The reciever calls this PCM, your PS3, when pressing select should show that it is decoding the dolby digital HD. There is no quality difference in the two. PCM is the same because it is un compressed audio. So when using HDMI, no matter the signal that the movie or music is playing, wether it be dolby or DTS, you will see PCM when using HDMI.
If it is a new DVD that may be a problem, as signal changes may be frustrating this old machine... but it is likely the cabling from the DVD player to the reciever. Are you on the right channels/settings? is the optical cable and digital cable recieving digital output from your DVD player? Try changing those settings and you should be in good shape
Thanks! good luck!
Have you changed your DVD player or it's settings? If the Dolby Digital light comes on then your receiver is working as it is detecting the signal format. I suggest that you check the set up of the DVD player and make sure that it is set for bitstream and not pcm.
