UnityPlayFullScreenVideo direct call from within Unity3D

Has Anyone successfully called UnityPlayFullScreenVideo via ObjectiveC within Unity3d and successfully got it to work. The main reason for doing this is i want the ability to load a vide full screen from within a device but not via the streaming assets folder.

Looking at the Xcode project it appears that if i give it a URL that has :// i seem to be able to get around the requirement that the video be streamingAssets only, but was't sure if someone else has a solution to this problem or has lessons learned from NOT doing or from doing it?

Care to share?
