Selfish friday night? When only 5%, as you mentioned, adjust their gamma correction -
why should a QT "gamma correction support" be "better than nothing"? For what 5%?

The kind of automatic correction has been available before MPEG-4. Just by not-touching
the monitors default settings. The way QT screws itself into gamma with MPEG-4 is,
again, just as rude as REAL.
