Ben, I may have misunderstood the MPEG-4 gamma correction. I remember you saying it
would automatic set the gamma to the computers default. This would be 'lite' for Mac and
'dark' for Win. Correct?

Now you wrote this auto-correction gets us a lot closer than before. - How, if it sets
to the default values of 1.8 and 2.2? Or is it creating a compromisee in the middle?
Only this, I'd say, would bring us closer together. Not resetting to the default
differences.

To ask more simple: Appears a movie on a Mac darker or brighter when the movie is an
MPEG-4 compared to the same movie in a non-correcting codec? To get platforms closer
than before I'd expect it to appear darker.

What if I have adjusted my monitor gamma already for this closer-getting-compromise and
write a QT MPEG-4 movie which looks fine on my Mac?
