Remember the first MGM DVDs back in 1998? If they were in anamorphic, 16:9 enhanced widescreen they were state-of-the-art new transfers, if they were only in letterbox they were a mere rehash of previously existing letterbox master tapes for LaserDisc.
Since I do own several English, French, Japanese and German versions of the Theatrical Edition on LaserDisc, I would humbly ask but insist of having a picture quality equal to the one of the Special, Ultimate, Archive or whatsoever-called newer version: Theatrical Edition in 16:9 enhanced widescreen.
In regard to the sound properties I feel we are automatically restricted to the 6-channel-magnetic Dolby Stereo sound that will not deliver the same punch like a modern Dolby Digital 5.1 or 6.1 movie.
Because that was the sound format and sound quality some of us experienced the Theatrical Edition during its initial theatrical runs. Asking for more would be hippocritical and the Special Edition would be the unavoidable answer...
