Save Movie Texture to iphone / ipad camera roll

Hello,

Is there a way to modify this command and instead of having "CancelOnTouch" have it "Save to Camera Roll" ?

function Start() { iPhoneUtils.PlayMovie("StarWars.mp4", Color.black, iPhoneMovieControlMode.CancelOnTouch); }

There are Apps that do this but I am not finding any information on how to do it in Unity.

Thank you, Scott
