one of the things I've noticed as an editor is that many of the added things on the SE could just be cut out if the original negative was truely altered in 1993. The only thing that would have to say in is the Mos Eisly conversation in the speeder, the shockwave effect from destroying Alderean and the wierd axis shift with the shockwave effect from destroying the Death Star. The stuff that stays could be covered with LD Stuff or even quality transfers from preserved prints. I could actually do this as an editor, all it takes is getting the equipment together and making the transfer one of quality.
