Quick question: Other than improved lightsaber effects and new music, what did Ady do to the Obi-Wan/Vader duel in ANH? I don't remember it being any different other than those two things.

He actually did a new edit of it. I can't recall specifics, but I think there are tighter cuts and some rearranging. Quite nice, especially when you didn't notice. Can't do that to ESB, since the fight is pretty linear, instead of two old guys spinning around in one room, who then move next to an open door.
