It should automatically select it when it detects the input. Most likely you have to go into your DVD player's menus and change Dolby Digital and DTS to bittstream, not PCM. Less likely you have to use the dolby selector on your remote untl Dolby Surround, or Dolby Digital is displayed.
No dolby selector, hmm i can't seem to select dd i have tried everthing i can think of. This is a 6.1 ch receiver could that be cause problems ??
Did you go through the DVD player's setup menu and change Dolby Digital from PCM to bittstream?
one problem no dolbydigital setup feature just audio out spdif/raw spdif/pcm pdif/off. This is a nova dvd player it says dolbydigital on front of dvd player. But my receiver isn't picking up single, dvd is dolby digital 5.1. There seems to be an option on dvd play that i can't access.
