yes, I tried the mp3player example, but diverted to using pygame.mixer 
as I need more channels and .wav and .aif support. I have this working, 
but sound.get_length() gives an attribute error.. (mailed the issue to 
the pygame list). So when Kevin O. will have quicktime working in wx, 
that would be perfect for my app -> can we test this?

Anyway, here's the relevant -commented out- code from the mp3player, 
but that works fine for me.

         ## NOTE WE DON'T IMPORT PYGAME UNTIL NOW.  Don't put "import 
pygame" at the top of the file.
         import pygame
         self.movie = pygame.movie.Movie(filename)
         self.movie.play()

         # it was a good idea at first, but mixer simply doesn't work, 
at least on the Mac
##        assert os.path.exists(filename)
##        from pygame import mixer
##        mixer.init(44100, 2)
##        mixer.music.load(filename)
##        mixer.music.play()
##        print mixer.music.get_busy()
##        #time.sleep(5)
##        #mixer.music.stop()

Why do you say in the first line pygame shouldn't be imported at an 
earlier stage in the code?
