It is by definition a Denon problem, since the receiver will not properly decode the bitstream. What Denon support should have done was to not dismiss this problem but instead to actually assist me. If it truly is THX metadata that is at the root of the problem, you would think they might want to get all the info they could about that from their customers. Like it or not, it is Denon's problem whether they created it or THX did. They have the obligation to follow through with helpful customer support -- not just to tell me to send in the receiver, and sorry I will be without my home theater for a few weeks (months?). C'mon, that's worthless support. It is a Denon problem and they will have to deal with it one way or the other. It is also an Onkyo, Panasonic, Samsung, Sony, (insert manufacturer name), THX, and Lucasfilm problem. But since I own a Denon, and that amp is not decoding the bitstream properly, it is a Denon problem. Of that, I am very certain.
