Cool, I'm glad to see there is demand for the 70mm version. Satanika just sent me the 5.1 AC3 a couple days ago, but I can't test it completely yet because I'm visiting my family and they don't have a 5.1 setup here. My preliminary listen in 2-channel on headphones showed that the volume level was somewhat lower than the source files, but I'm not sure why since there is no dialnorm or DRC in the encode. Perhaps it is just my computer being funky with the playback, and bitstreaming it out will yield the proper sound. I should be back home and able to test it out early next week--I'm hesitant to make it generally available until I'm sure nothing is wrong, but it's definitely worth waiting a bit for, because the full sound complete with LFE channel is entirely awesome.
It would be kinda neat if this version included the 35mm stereo, mono, and 70mm 5.1 soundtracks all together, so the complete theatrical auditory experience would be available on one disc. ;)
For Empire and Jedi, 70mm recreations aren't strictly possible, but the '93 and 5.1 soundtracks on the previous versions already sound great. I've been considering doing small revisions on Empire, to substitute the hacked up music cues with how they are in the SE and add the missing snowspeeder sound, but those are only minor changes. Jedi I believe I am quite satisfied with as it is.
How much of an improvement are G-Force's new scripts compared to the earlier ones? I'd been planning on doing encodes myself, but my computer takes about a week to do each one, which is kind of inconvenient.
