32 bit workflow in After effects CS3

Hi everyone,
I have been using Prospect HD for a while now and I would like to do my color correction in After Effects and benefit from the 32bit mode.

My master should be for SDTV Pal. However I don't know which Color Profile I should be using in order to work properly in AE w/ Cineform encoded files.

In the project settings I change to 32 bit mode and set the working space to SDTV Pal. Than I check Linearize working space.

However when I import a cineform encoded clip there is a gamma shift (darker). Now I understand that the video should be corrected. So I go to Interpret footage and in color Management I don't know which Color Profile to select?

Should it be HD Rec 709 since the video is HD? Or should it be SDTV Pal? Or should I use a another profile as in the tutorial from Stu Maschiwitz: fxguide - vfx knowledge - After Effects 32-bit Workflow In-Depth

Maybe I should work in another working space? It's very unclear. In AE 7.0 I used the linear profile as described in the tutorial by Stu but in CS3 it seems that there is by default a linear working space (the checkbox linearize working space).

Any suggestions?

Thanks a lot
Simon

Ok I noticed that in Interpret footage > Color Management when I select Preserve RGB the video returns to its original state.

Is this the correct way to use cineform files in 32 bit mode? Whatever the Working space in 32 bit mode?
