I'm trying to use the MPMediaPlayback protocol's currentPlaybackRate() to slow down a video. I'm confused though as the class MPMoviePlayerController states that:

You can control most aspects of playback programmatically using the methods and properties of the MPMediaPlayback protocol, to which this class conforms.

Except just above in the header here: http://developer.apple.com/iphone/library/documentation/MediaPlayer/Reference/MPMoviePlayerController_Class/MPMoviePlayerController/MPMoviePlayerController.html it doesn't seem to.

All I want to do is slow down the playback rate for a video.
