Wow! Looks like quite an interesting project, OmegaMattman. The screen shots look quite nice, and I love the cover art. This HD conversion of the GOUT sounds fascinating. As for color correction, I'm glad that you color corrected the opening crawl separately, as its color is, as you mentioned, distinctly different from the rest of the movie.
Unfortunately, I'm running low on blank media right now and cannot test this.. However, I would suggest using Hairy Hen's 5.1 70mm reconstruction audio for this. The 5.1 mix is already set up to sync with the GOUT, so there's no problem there. It's very good and has been used in several projects.
