(technical answer, so it belongs to mplayer-dev and not -legal :-)

ATM it uses libSDL that uses QuickTime. You can't display
YUV on MacOSX without QuickTime, so a native driver would
use QuickTime directly. In theory you can display RGB with
only Quartz, but it would be unbearably slow, and nobody
does that (well, the x11 driver of mplayer does, and it *is*
sloooow :-)

QuickTime is to Quartz what the Xv extension is to X11.
It has always been true (except before MacOSX, the 2D
display was QuickDraw, not Quartz).

The name "QuickTime Player" for the media player is only
a name, it's not part of QuickTime at all, and never was.
Apple ships it like Debian ships xine (yes, mentioning
Debian *is* a troll, sorry :-) that itself use Xv.

HTH.
