I just discovered your edit after discovering this board! After what seemed like an eternity of torrent time, I finally have it and it looks beautiful!
After being so disappointed in the release of the original, unmodified trilogy to DVD in 4x3 letterbox, your solution definitely rides to the rescue.
Thank you for what must have been hours of grueling, tedious work to restore what most of us here otherwise consider a masterpiece of film.
