Matt,
I've been wrestling with DVD-A and DVD-V layers on DVD-A discs lately. On most DVD-A discs, you can only get to the DD or DTS tracks by accessing the DVD-V layer on the disc. I believe this is usually achieved by selecting an option in your PLAYER'S menu (not the discs menu). My Denon DVM-2815 does NOT have this option and thus on discs that offer DTS/DD as well as the true MLP/PPCM hi-rez tracks I cannot access the DTS/DD stuff. I can see them if I put the disc in a non-DVD-A player (different disc menu offered-up when I do).
Note, however, that I have some discs (A Night at the Opera for one) that have the DTS track as an option on the main DVD-A menu and I can access it just fine. But, on Steely Dan's Two Against Nature, The Eagles' Hotel California etc, I CANNOT get to the DD/DTS tracks in my 2815.
You may have the same issue with the 1600 but it seems the 2900 does offer the player menu option to allow you to get to the DVD-V stuff so each player is different.
Your are seeing DPLII etc when you switch to your digital input as you are just receiving a PCM stereo signal over the digital connection regardless of track selected from the DVD-A disc. The digital connection is not capable of transmitting multi-channel hi-rez data (DD/DTS being compressed).
Althought the hi-rez tracks are going to offer the best stuff on the disc, it's frustrating that I can't access all the available work on a disc.

Note that no one has responded to my last question in the above thread about whether this lack of access to DVD-V is common on DVD-A players.
SteveK,
If the player has an internal DD and DTS decoder, it will send decoded DD and DTS over the 5.1 analog connections if you desire. It's usually a better option though to have your receiver do this over a digital connection from the player.
