With the two DVD-A/universal players I have had (neither was a Denon), there was something like a default audio mode that had to be set in the player's set-up. If it is set to DVD-A and you load a DVD-A disk it will show the DVD-A multichannel in the main menu. If it set otherwise, it will behave like a regular DVD player and default to Dolby Digital track. So my guess is it is the 1920's set-up that needs to be changed. You will also have to set the DVD-A and SACD output to go to the 6-channel analog outputs for use with any Outlaw processor.
