Not sure if this is true for all players but for my Panasonic, the Dark Knight disc starts right into the movie with no menu to look at. When I first watched it I did not think much of it other than the center channel seem quiet and I had to really crank it to be able to hear dialog. Of course this mad everything else really shake the house.
After the movie I pulled up the DVD menu to find that the disc automatically starts in Dolby digital and not Dolby TrueHD 5.1, I re-watched the movie in True HD and the audio was very much improved.
