The whole idea that fans, using (mostly) home video releases, could create a better-quality product than studios who actually have access to film masters and tons of expensive equipment seemingly defies logic.

Have you watched Adywan's Revisited fan edit? This fan edit alone shows how one person can create a professional-looking edit using affordable home technology and software.

I would suggest that someone new to the Star Wars movies would never suspect that ANH:R isn't the officially released movie.
