All Darc, I appreciate your suggestions. Since there are no color shifts between versions apparent in the master tapes, I have asked the DVD place to look into it.
However, it is clearly noted on the Blu-Ray web site that their frame captures are highly processed and it is possible that an error was introduced which does not exist on the actual Blu-Ray.
As to your suggestion that the 20 fps version be achieved by speed-slipping the 24 fps version, here's what I wrote to someone else:
Both runs are from the same negative, but they are two separate transfers; one is not converted from the other. I was told that trying to slip the 24 fps transfer by 20% would introduce many artifacts. (It would have cost a whole lot less money to slip speeds, had we been able to do it). The digital algorithms for stabilization and cleanup are much less effective at 20 fps than at 24 fps; however, sharpness and tonality should be equally good at both speeds. Further, as I was given to understand matters, progressive scanning doesn't work in HD at non-standard speeds. I am not an engineer and am completely green to the world of HD so count on the opinions of those who know more than I do, which includes most of the people who worked on this thing.
