I did not experience the bass problem that @MCDave reported either on PCM or DTS. On the contrary, the bass lines are much more prominent on the 5.1 & stereo mixes than the original '80s mix. I never really heard before how detailed some of the bass lines were. Perhaps MCDAve meant that the low end output wasn't lighting up his subwoofer?
Yes, that's what I meant. Like you and some others, I too found the bass guitar much better defined than in the original, but it's the deep bass punch that was lacking for me. I've got 2 huge subs with 4 x 12" drivers, and on virtually all of my other surround titles they produce a gigantic, bigger-than-life bass slam. The Gentle Giant mixes come to mind here. Bass normally shakes the room on any other title, but on this one it was like listening with the subs unplugged. That's why I had to check them to see if they were outputting anything. They were, but I could barely detect it with the palm of my hand 3" from the center of the woofers.
I seem to be the only one reporting this, so I'll have to have another listen to confirm.
