Okay, I exchanged the John Carter (Four-Disc Combo: Blu-ray 3D/Blu-ray/DVD + Digital Copy) at a Target store in another city to try to eliminate the possibility of a bad batch of Blu-rays. No luck. The new 2D Blu-ray still exhibits the same echo problem played on either the Sony 350 or the Panasonic 210. I am planning on writing Denon support to state the problem and what I've done so far to find a cure. The echo comes and goes in the soundtrack but I can always replicate it in the same spots. One prime example is at 44 minutes into the movie during the flyer battle when John Carter catches the Princess in mid-air. The dialog suddenly moves from the center channel to the left and right speakers with a slight delay leading to an echo in the sound. This Sunday I plan to play this Blu-ray on my daughter's system which includes the Denon 1612, PS3 and Panasonic DMP-BD75.
