So digital bits wants Lucasfilm to do something about the discs...interesting. They'll probably come back with some lame-ass attempt at an excuse like, "The age of the film's audio led to several limitations in the conversion to digital home video. As a result, some of the films' soundtrack may not sound right."
I'm contacting Lucasfilm because my DVDs seem messed up as well: there is a strange glitch where Han Solo shoots Greedo...
