Ok so I realized that I did not previously set up my dvd player to send the correct info to my receiver. Dolby Digital now works - it must not have before because my receiver now says it on the front display. My question is this. In Dolby Digital, when I play a James Taylor concert I have, his voice can be heard in the front left, center, and front right speaker. Another JT dvd I have his voice is only heard in the center speaker. And I have a Rush concert dvd where the voice is heard in the front left and right but not in the center! I guess there's some logic in this when they set audio up but why is this?

Ah yes.. I am indeed trying to learn :-)
