I got the original THX 1995 pan and scan tapes, and DVD transfers of the same set in widescreen that were copied from the VHS that I got at a fair. You can tell on e-bay, if its a good picture and you can read the back, under the credits it would say:
THIS FILM HAS BEEN MODIFIED FROM ITS ORIGINAL VERSION. IT HAS BEEN FORMATTED TO FIR YOUR SCREEN
