function YoutubePlay(){


// Start download
var youtoobMuvee = new WWW(youtubeString);

// Make sure the movie is ready to start before we start playing
var movieTexture = youtoobMuvee.movie;
while (!movieTexture.isReadyToPlay)
yield;



funkBox.renderer.material.mainTexture=movieTexture;
audio.clip = movieTexture.audioClip;

// Play both movie & sound
funkBox.renderer.material.mainTexture.Play();
audio.Play();
}

Getting a youtube vid , applying it as a texture to a gameobject and playing it with sound doesnt work , i am getting these errors

!texture.texture
UnityEngine.MovieTexture:get_isReadyToPlay()
UnityEngine.MovieTexture:get_isReadyToPlay()

failed to create 2D texture
UnityEngine.MovieTexture:get_isReadyToPlay()
UnityEngine.MovieTexture:get_isReadyToPlay()

what am i doing wrong here?
