Levels and Color Shift

I am importing Uncompressed 10bit 1920x1080 23.98 footage into After Effects and rendering it out the same way. When I reimport that render into AE and drop it into the same composition, it does not look like the original file. The levels are off.

Notes:
- CS3 8.0.1
- I have removed all filters when doing this test and color management is off.
- I drop the levels filter onto the original file and the rendered file, just to see the histograms for both, and it appears that the levels for the rendered file have expanded.

As you can guess, this is causing problems in FCP. The rendered file does not look like the original file. Any ideas?

Also, the footage did originate on the HVX200 (DVCPROHD 1080) but was rendered out of Final Touch in Uncompressed 10bit 1920x1080 23.98.
