The idea for the Ultrapurist Edition is great, and something that is sorely needed (after all, it's why this place was created, right?). I've been thinking about the same thing lately, working from Adywan's colour corrected set, keeping the blooper fixes, and going from there to recreate the original unmassacred film in pristine picture. Thing is, though, that I have absolutely no knowledge on video editing software, so I'm very glad to see someone else give serious thought to doing this.

A couple of the trickier scenes to work with, off the top of my head, would be the Sarlacc Pit and the ending in RotJ. They're also two of my favorite :/

Anyway, full support for this project from me :D
