Yamaha HTR-5640 Question

Hi, I just set up my system this evening. My problem seems to be that I'm not getting digital sound output from the receiver. I have a 6.1 speaker set-up hooked up with a dvd player. The digital audio is being sent via optical. The speakers are all working as I can test them fine, but whenever I put in a movie, the receiver doesn't show the 6 speakers (or 5 if the signal is 5.1) on the display. No matter what I select I only get the L and R speakers on the display. The sound from the movie is coming out all the speakers, but I think it might be simulated, which I don't want. I've read the manual and all that, but it hasn't helped me. Does anyone have any experience with Yamaha receivers to know what I'm doing wrong? Thanks!

Did you set the DVD player to bitstream in the set-up menu? If you're not sending 5.1 to the receiver it won't detect it.

Is the input mode set to auto in the receiver set-up menu?

Hope this helps.

Genius, man. Pure genius. Was the dvd player. I can get a good night's sleep now! Thanks a lot!
