I always heard the missing lint shot was just an error. I'll have to check mine out.

These are all LD masters, same print defects, same slightly tweaked video levels for older CRTs; the DVDs just give you a better quality video presentation.

The first film needs a capture badly as none of the remixes touch it. In fact, it would be possible to make a 5.1 recreated 70mm mix because I'm pretty sure the audio was the same. (4 channel with baby booms)

Returns is the same mix in 5.1 and DS. However the emphasis and soundstaging is very different. The 5.1 utilizes the discrete channels to good effect, but the DS is much more centralized and gives a better sense of low end, as is the case with Batman Forever's 5.1 vs. DS. Additionally 99.9% of people heard Dolby Stereo theatrically as only 11 theaters were equipped to show Dolby SR-D 5.1 at the time. Judging sonically, they really mixed for Dolby Stereo before getting the go-ahead for a 5.1 mix.
