Answer by Naina Soni for MPMoviePlayer play on when application goes Background

You need to do remote control setting in combination with Background support setting in ios5-

// register your app for remote control

if([[UIApplication sharedApplication]  respondsToSelector:@selector(beginReceivingRemoteControlEvents)])    [[UIApplication sharedApplication] beginReceivingRemoteControlEvents];// allows you to play in the background when app is suspended in iOS5[[AVAudioSession sharedInstance] setDelegate: self];[[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayback error:nil];

Place both the settings in application didFinishLaunching delegate
