ESB fixes:
Fix the continuity error created by the "new windows" (now you see them, now you don't) on Bespin between the time Lando is showing them the tour and they get detained by Vader's men.
Restore Fett's old voice.
Correct the asteroid that has an explosion in it right before the Falcon and TIE's reach it (for no apparent reason). If it's going to be a collision it shouldn't flame up like it's a laser hit or something.
Fix the problem where Luke's saber is still on as he leaves the cave (yet you hear a saber off sound).
Restore Luke's line "You're lucky you don't taste very good" in the swamp
Fix any instances of "black R2D2 panels" in space.
Fix the transparent cockpits in the snowspeeders (for good this time)
Remove the obvious "puppet stilts" in a few shots of the AT-AT's.
Fix the saber colors, making them more consistent with the other movies.
PS: With the SE Wampa footage, you now hear two roars (roars as the wampa is eating and grunting), as if there are TWO wampas in the cave. Decide if you want there to be two now or just one...
