Not exactly 70mm because we can't know what audio differences were present, but my versions capture the general feel of what they would have been like, if not the specifics. The RotJ mix I refer to above is the one present on dark_jedi's previous encodes. Sorry for causing confusion about different versions; it comes from the fact that successfully recreating a theatrical mix will automatically garner more interest on this board than something that is a fan-made hybrid, which is what my other mixes are.

Anyway--I just started a new job, and so haven't yet been able to send the ESB files to Satanika as I had planned, but I will be doing that as soon as I can.
