If there is any way possible to sync-up the audio with the video, the Anakin/Obi-Wan duel MUST be slowed down. Why they sped it up in the computer is beyond me. The footage in the "Return of Darth Vader" featurette was perfect. The rapidness of it all doesn't allow for the emotional ressonace of the ESB duel, for example. The Dooku duel is my favorite of the film, because while fast, it isn't flying by you at light speed and you can take it all in. Coupled with additional scenes of the duel on Mustafar, I believe this will improve the ultimate confrontation.
The shot of Yoda and Sidious rising up in the Senate Chamber had the potential to be as epic as the great pan-up in the Theed Reactor Room to the lightsaber duel. However, the shot was rushed and cuts to a close up before the phrase of the music ends. If this shot is slowed just the littlest bit, it will be infinitely more effective.
Yoda lines that must be cut:
"Not if anything to say about it, I have."
"...and not short enough it was."
