Have you checked out the NTSC version? It was painstakingly converted from 25fps to 23.978fps (rather than the usual IFO tricks which use the PAL soundtrack for compliant, if not truly converted, NTSC video) and pitch corrected so it sounds like the Empire we all know and love yet still showcases Jambe's marvelous work on this project. I say painstakingly because it took a month of trial and error to get it right due to some weird conversion glitch. The Jedi one went flawlessly and took only a few hours (it's never been distributed, though and only Jambe and a couple others even have a copy).
