If I understand correctly, you want to play the mp3 playlist on OS 3.1 using a standard media player without having it on the screen.
If this is correct, I suggest you move the application window on top of the video screen using this:
appDelegate.window.windowLevel = 2
If your main window is opaque, you will not see the player, never. I donβt know if the native player supports M3U files, in the worst case you need to intercept the MPMoviePlayerPlaybackDidFinishNotification event and then play the next file.
Hope this helps.
