I think there's some serious truth to this, though. He's changing his classic films from the 70's and early 80's because for some reason he's trying to convince himself that his divorced life is better than his old life used to be (subconsciously), and therefore the films he made back in the "flawed" part of his life all need to be changed. I know his wife helped edit the original SW; maybe he wants to have the "final say" or "finish it off" so as to make him forget.

In my opinion, that's why George Lucas edited the Star Wars Trilogy (and THX-1338), because it's so ingrained in his mind that since his life was flawed during that period, so was everything he did, including his films, and to be happy about his work, he had to revisit it during his "happier" period.
