My mixes were put together by Satanika and I by upmixing a slightly edited version of the '93 pcm track from Belbucus, and combining it with a level-adjusted and GOUT-synched LFE channel taken from the special edition, then encoding to ac3 at 448 kbps. The primary goal was to recreate the 70mm mix of Star Wars in 5.1 (which Harmy used for his PDE version of that film), but I also made 5.1 for the other two movies to go along with it. Understandably, he decided not to use the one for RotJ, because I added the deleted music in the scene with Obi-wan on Dagobah. To me the scene is immensely improved by this addition, but obviously not everyone will agree, and since this was not actually a part of any original mix, it isn't really a preservation per se.

It does, however, have an excellent sound, due to the superior balance of the '93 mix over the special edition (the surround does not become deafening every time something moves to the back), and the addition of LFE gives greater impact than a stereo track alone. It synchs perfectly to the ntsc version of the gout, so it should also work here, assuming this has the same frame count. For my own part, I'll probably mux it to the ntsc dvd video, but I completely understand wanting to keep things as original as possible, so I recognise that it won't be of interest to everyone.

Darth Mallwalker is correct that the one on usenet is a rough older version. The perfected track is linked to at the end of this post, if anyone else wants to use it: http://originaltrilogy.com/forum/topic.cfm/Star-Wars-1977-70mm-sound-mix-recreation-stereo-and-51-versions-now-available/post/403997/#TopicPost403997

I'm pretty excited to see what Harmy has come up with. Between this and adywan's ESB, there's only the original film left to do in high quality. Out of curiosity, how much colour correction was done for this project?
