objective c composite dock connector
===

I am developing a simple App to use for myself when I'm away to stream video to my iphone.  At some point I bought a composite video connector to play the video on a tv or projector.  Not unlike this one here http://www.amazon.com/Dynex-DX-IPAV1-Composite-Cable-iPhone/dp/B005Y4A98U

When I plug the cable in, audio is automocatically sent through the cable, but I can't figure out how to enable my app to be able to use the connector for video as well.  Perhaps I am just being hopeful, but when I play a video through a web view, or the youtube app, video is sent to the tv so I am assuming there is something I am missing in my app to be able to do a similar thing.  I've googled around a bit and searched here, but I guess my google-fu is not as strong as it used to be.  

Currently my app uses MPMoviePlayerViewController to play the live video stream 

relevnat code here

    NSString *urlString = ([[AppDefaults appDefaults]remote])?REMOTE_HOST:LOCAL_HOST;
    NSURL *videoUrl = [[NSURL alloc]initWithString:[urlString stringByAppendingString:VIDEO_STREAM_URL]];
    
    player = [[MPMoviePlayerViewController alloc]init];
    player.moviePlayer.allowsAirPlay = YES;
    [player.view setFrame:CGRectMake(0, 0, 320, 240)];
    
    player.moviePlayer.movieSourceType = MPMovieSourceTypeStreaming;
    
    player.moviePlayer.contentURL = videoUrl;
    player.moviePlayer.controlStyle = MPMovieControlStyleEmbedded;
    
    [self.mpcontainer addSubview:player.view];
    
    if(player){
        [player.moviePlayer prepareToPlay];
        [player.moviePlayer play];
    }




any thoughts/suggestions welcomed
