About the 1997 Star Wars mix: yes, I would indeed be interested in the DTS to use for my 70mm project. I've been limited to using the 384 kbps AC3 from laserdisc, so a higher bitrate version would certainly be a good thing, if it can be managed. I only actually need the LFE and not the main channels, since that's the only part that the SE is actually used for.

hairy, I'm not familiar with your 70mm project, but I will surely check it out. I do have one comment, however. The LFE content from the DTS track may not be entirely synchronized with the AC3 track. There may be splices at different time codes which may lead to sway throughout the entire movie that would have to be edited and adjusted by hand. I'd recommend sticking to one mix for the sake of synchronization between channels.

edit:

I'm now familiar with the soul of your project and understand what you're going for... and the work that you put into it :) Since you will be editing by hand, the LFE from the DTS may be worthwhile.
