Hello, everybody.

We all know the changes GL made in the special edition(s), both the visual changes and audio changes. But I wonder what's the difference between the mixes? The official Blu ray claims to have 7.1 surround sound, but since I don't have a 7.1 surround set-up, I can't confirm it. So, for those of you that have that kind of set-up hooked up to your Blu ray-player, what does sound like? Is it simply a up-mix of the 5.1 mix from the DVD or is it a new mix altogether? And, while I'm at it, is the 5.1 mix from the DVD a up-mix from a stereo mix? Can someone help me?
