I don't mind all of the SE additions, some of them were valid and beneficial to the movie (new Sandcrawler scene for example) but I too would love to have a better archival version of the theatrical versions, warts and all :)
EDIT: I came across a Star Wars REIVAX version, it claims to be from a digital betacam broadcast and thus better quality than the laserdiscs. Is this so and does anyone have some comparison shots?
