That confirms my suspicions. GF and TB SE DVDs come from their respective THX box sets. The others are straight from their home video telecines.
The color on GF looks great on the THX and SE, but maybe that's because I'm used to it. The Criterion color still seems off to me.
From what I know about the missing GF frames, I think it was first cut out by MGM for the THX box set.
The only way we will ever get perfect versions of the Bonds is if we obtain original IB prints of the films, and British ones for the first three.
