Because it's the system graphics library. It links with the QuickTime 
library, not with the Quicktime program itself, just as it links with 
the other system libraries. It just so happens that the QuickTime 
library can see and use additional plugins, w/o specifically 'linking' 
to them, It discovers and loads them at runtime, when the media 
requires it. Anyway, i see it as a 2-way door. mplayer uses quicktime 
on os x, and i do not see why the flames given were required. And yes, 
i have RTFF.

I think you've been smoking Cocoa instead of coding with it....
