I am trying to figure out how to add a custom control to the iPhone MoviePlayer. For an example of what I am trying to do see the following image.
This sample application that Apple provides should help. From the description:
Demonstrates how to use the Media Player Framework to play a movie full-screen. The sample contains code to configure the movie background color, playback controls and scaling mode via the built-in Settings application. Also shows how to draw custom overlay controls on top of the movie during playback.
