Since there has been some concern about the idea of using music-edited mixes in preservation projects, I've asked Satanika to help with making additional 5.1 versions of Empire and Jedi that more closely resemble the 35mm/1993 versions and do not contain these edits. So, assuming that he is able to do this, there will be more 'authentic' versions for those that prefer to hear the films that way.
Fans of the snowspeeder crash sound need not worry, for this effect will still be heard. ;) Essentially, in terms of content, both will be 5.1 representations of the 35mm versions of each film. I did not attempt to replace the main title music in Jedi, as indicated above for its 70mm mix, because I don't think there's much point in doing so, and a few parts of the special edition LFE bass may not have been there originally, but aside from that it should be fairly close to what it's supposed to sound like. All that's really missing now is the 70mm Empire mix, and since that's quite a separate and elusive thing that wouldn't even synch to the GOUT video anyway, we should pretty much be all set for sound mixes. Obviously we still don't have the discrete channels of the originals, but it's about as close as we can get with what's available.
I'll probably still watch them with the music-edited versions, just because I like the way they sound, but hopefully now everyone will be happy. :) I think of all the films I'm most fond of the sound of the original Star Wars, and in its 70mm form it finds its most ideal presentation. The only thing I really miss when hearing it is the 'deceleration' sound from the mono mix (when the Millennium Falcon comes out of hyperspace), but other than that it is nearly perfect--so much so that I wonder how anyone could feel the need to incessantly remix it and move it further away from what made it sound great in the first place.
