to bring in some comments about dubbed versions: The german OT SE introduced a 2nd voice for Luke, used in the reinserted Biggs scene at the end of EP4. It introduced a 2nd voice for Darth Vader, used in ESB for the 'Bring my Shuttle' scene. Both voices don't(!) fit well.

The 2004 ESB DVD introduced a 3rd voice for Darth Vader, used for the Emperor Hologram scene. And a 2nd voice for the Emperor, in the very same scene.

It's a shame having a character using 3 voices in one single movie.

At least the Ep4 fanfare is intact in the german audio, so are the lines spoken by Boba Fett dub actor, they were overseen (or untouched) by LFL in 2004.

So the more GL is changing his saga to fit it together, the more it falls apart in its international versions.
