If anybody has a copy of the first DVD release and wants to extract the AC3 track and send it to me, I will be glad to perform a detailed analysis of it and find all the specific ways it differs from the remixed version. As those who have followed my work on the Star Wars preservations know, I am rather good at doing that. ;)
I will post all observations in this thread so we can lay it all out clearly, rather than relying on rumor and speculation.
