I need advice...
I am doing some simple compositing for a client. The footage was shot on 35mm film. In telecine they output the color corrected scenes as standard def 720x486 uncompressed Quicktime files. The editor did an initial online with the color corrected scenes in his Avid. He then exported from his timeline only the scenes I needed in Avid Packed Codec compression. He exported each scene both as RGB and 601 color space. I have tried a myriad of color management options (including "None") on both the RGB and 601 files. When he imports my compositions back into Avid, the colors do not match exactly.
Any ideas what we may be doing wrong?

It might be Quicktime that's giving you fits.
Within the past year, Apple messed with QT's Gamma settings, changing them from something like 1.8 to 2.2. So if your editor has an QT version that's a little older, it could be the culprit. A visit to the Apple Web site and searching the discussions for the gamma issue may be well worth your while.
Whenever I run into this problem, I just fool with the Gamma... but I bet your standards are somewhat higher than mine.
