The 1992 are from the same masters as the earlier releases before the THX remastering, so even though they don't have the rot problems of the earlier releases and have digital sound, they don't look spectacular. Though they do look better than the VHS tapes from the same era.
The 1995 pan and scan faces VHS looks a lot better, but they cleaned up the picture with Digital cleanup.
Both have been preserved in the past by dark jedi as preservations.
I cannot be of any help to you however since all my copies are now rotten.
