Slight update to incorporate the [G]OUT DVD releases into the list, now replacing the various laserdisc transfers as the best source (so far) for that version.
Exception made for the original Star Wars: the [G]OUT DVD release of that is more of a simulated 1977 version than a real one, due to it being a composite of the 1981 and 1977 versions.
MODS: Can we sticky this thread for the "Theatrical Cuts vs. Special Editions" topic?
