Couple of things you should check out. Make sure that DRC, Midnight mode, etc are all turned off. On the Denon and the Player (not sure what you have). In some cases, the movie tracks may have DRC turned on my default. And on Denon, you won't see the DRC setting for TrueHD unless you are bitstreaming TrueHD (only visible while the bitstream is happening. You should also look at the Audyssey setup FAQ over at AVS.
