Also, was the sound completely/majorly remixed for 2004 DVDs, or is the 2004 mix largely the same as either/both of the 1997 mixes (apart from obvious changes like Emperor, Boba Fett, etc.?)
Star Wars was completely remixed. (In a terrible fashion; the 2004/2011 mix is atrocious). ESB and ROTJ are mostly the '97 mixes with more changes.
