Gamma issue in exchange with Flame `09

The issue is:

We played out some footag on digi beta and created from the same sequenz a QT 10 bit uncomp.
We captured the digi beta footage and imported the QT into the Flame ´09. The result was that the imported QT seems to be a little darker than the capured footage. (looks to us like a gamma shift)

We are working with FCS 3.0 and QT Version 7.6.2 Pro and Flame 09, what could be the reason for this kind of issue? did you have any similiar issues or experiences with this kind of workflow?
