A run loop, like this for example:

=======================

#!/usr/bin/env python

from QTKit import QTMovie
from AppKit import NSSound, NSRunLoop
from Foundation import NSDate

movie, error = QTMovie.movieWithFile_error_("Happy.mp3", None)

if movie is not None:
     duration = movie.duration().timeValue / movie.duration().timeScale
     print "QTMovie Media Length is %d Seconds." % duration
     movie.play()
     while movie.isPlaying():
          
NSRunLoop 
.currentRunLoop().runUntilDate_(NSDate.dateWithTimeIntervalSinceNow_(1))
         print movie.currentTime().timeValue /  
movie.currentTime().timeScale

=======================
