Basically he said that when he did the "special edition" version, they worked straight on the original reels and hence lost the original versions. All that was left was the Laser Disc remasters that were made a while back or so he says. Which is bullshit since more than one reel are made while making a money. It's just like Dogmatic said, Lucas hates the original version and sees the special editions as the definitive versions. Thats why he doesn't wanna spend money on remastering the original versions when he doesn't even like them.
