Someone posted somewhere that Lucas saved all the original bluescreen shots, which enebled them to recomposite all those shots again for the Special Edition. It was noted on Starwars.com about a year and a half ago that for the shots of Ben talking about Vader in the ROTS trailer, they pulled one of them from the original dalies shot in '76. Lucas is a known pack-rat of all of his film sources. You don't think that Lucas has the original film negatives, or at least high-generation prints of the original films (or both) sitting in his vault in San Francisco? Please. Mverta claims to have personally seen hi-def OOT source material that has already been transfered. To believe Lucasfilm when they say that the D1 LD master tape is the best source of the OOT they have is just naive.
