Didn't notice this before:
A 2-disc Platinum Edition was released on DVD in October 2006. There are a handful of changes, as well as some things that only appear to be changed.
* The most noteworthy change is that the infamous priest's knee has been smoothed out the first time it is seen. (For those who prefer accuracy, poke around disc 2 a little bit and see if you find some consolation.)
* When the credits start crawling, they are sped up a little bit to accommodate several restoration credits near the end. The total credits time is unchanged.
* The original Dolby Stereo logo has been replaced (as in the 1997-8 re-release) with newer sound specifications (SDDS, Dolby Digital, DTS) in the credits.
* At the end of the credits, "cassette and compact disc from" no longer follows "soundtrack available on"; as well, as with the re-release, a new Walt Disney Records logo is used. What has not changed:
* The original movie has some computer-generated elements (such as the ship and a staircase Ariel runs down); these are not new, and have been in the movie from its first release.
* While the re-release used a shorter version of "Under the Sea" in the credits, followed by Ariel singing "Part of Your World," the original version (and the 2006 DVD) feature a slightly longer "Under the Sea" and a wordless choral arrangement of "Part of Your World," so the audio for the credits is faithful to the original.
I've also been made aware of a more limited release that contains a DTS mix. Though not only do I not know where to get a copy, I'm not aware of any editing software that works in DTS. Maybe a v2.0 down the road(?)
ALSO Can anyone confirm for me that the 1997 re-release audio mixes were derived from a 2 channel source? I had read before that that was the case, but IMDB shows an original release 70mm 6-track mix. That would suggest there was already a pre-Dolby Digital more-than-2-channel-mix they could have sourced.
