Movie Texture will not play!

Hello!

I have this code attached to a cube with a gui texture. But it will not play! Any suggestions to what I have done wrong? Any help would be greatly appreciated.

 var wwwData : WWW;
    var url : String = "http://dl.dropbox.com/u/23413053/walkcyclemesh.mov";

    function Start () {
    wwwData = new WWW (url);
    guiTexture.texture = wwwData.movie;
    }

    function Update () {
    var m : MovieTexture = guiTexture.texture as MovieTexture;
    if (!m.isPlaying && m.isReadyToPlay)
    m.Play ();

    if(!m.isReadyToPlay){
        GUI.Label (Rect (410, 605, 100, 20), "Loading");

        }

    }

You have those two links...

Here’s the code for what I’d personally use:

var url = "http://www.unity3d.com/webplayers/Movie/sample.ogg";
function Start () {
    // Start download
    var www = new WWW(url);

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

    // Initialize gui texture to be 1:1 resolution centered on screen
    guiTexture.texture = movieTexture;

    transform.localScale = Vector3 (0,0,0);
    transform.position = Vector3 (0.5,0.5,0);
    guiTexture.pixelInset.xMin = -movieTexture.width / 2;
    guiTexture.pixelInset.xMax = movieTexture.width / 2;
    guiTexture.pixelInset.yMin = -movieTexture.height / 2;
    guiTexture.pixelInset.yMax = movieTexture.height / 2;

    // Assign clip to audio source
    // Sync playback with audio
    audio.clip = movieTexture.audioClip;

    // Play both movie & sound
    movieTexture.Play();
    audio.Play();
}
// Make sure we have gui texture and audio source
@script RequireComponent (GUITexture)
@script RequireComponent (AudioSource)

Obviously the url will change. I'd put this script on the texture, yes, as it does say this returns a texture, so I'd assume that it'd return the movie to the new texture... Comment back if you need more help though.
