Hello Jelle,

Your movie is not too bright, its contrast is too high.
Most likely this is full range video (brightness 0-255) displayed as video
range (brightness 16-235).
One cause of this may be that the video is accelerated by the video card in
one case but not the other. Video cards ususally assume YUV video is video
range.
Unfortunately there is no API for this like the gamma API (not that the
latter is fully reliable).
What is the source of this video? 

>In QuickTime player: Movies -> Show Video Controls does NOT exist!
(v6.5.2).<

Over here it does (on my Mac with Mac OS 10.3.6).

Jan.
