You were wrong on the disks (and you just found the most obvious one because all of Foxs titles use DTS-HD MA) but there are more studios and titles on bothe sides

I don't know if they are liars, misinformed, or just out of date or could just be the guy was talking about the value of DTS-HD (and DTHD) decoding in the receiver and just added a useless comment.

I will be on Vacation for the next few days, you have until I come back to find the answer by yourself.

PS not currently out, but you could also search on the specs of some of the new HD DVD players from Toshiba and their specs :) to show how dumb that statement actualy is.

PPS didn't this discussion start off when you said video 1.0 player won't do PiP and so the person needs to buy a new player. And I responded that there will always be features missing from some player and DTS-HD was only one of the examples of what a current HD DVD player can't do and someone loses out on some of the features that came on their disk? If it was easy and all players ever sold had that feature it would not have made a good example.
