video & mobile

hi everybody, I wanted to know how to read a little intro video in a mobile application?

For now, I have this code that there is supposed to work on phones but when we tested, it does not work :/

 using UnityEngine;
 using System.Collections;
 
 [RequireComponent (typeof (GUITexture))]
 [RequireComponent (typeof (AudioSource))]
 
 public class SplashScriptScreen : MonoBehaviour
 {
    public float m_timer = 12.0f;
    
     public string m_loadLevel = "MainMenu";
    
    //the GUI texture
    private GUITexture videoGUItex;
 #if UNITY_STANDALONE_WIN   
    //the Movie texture
    private MovieTexture mTex;
 #endif   
    //the AudioSource
    private AudioSource movieAS;
    
    //the movie name inside the resources folder
    public string movieName;
    
     void Awake()
    {
       //get the attached GUITexture
       videoGUItex = this.GetComponent<GUITexture>();
       
       //get the attached AudioSource
       movieAS = this.GetComponent<AudioSource>();
 #if UNITY_STANDALONE_WIN      
       //load the movie texture from the resources folder
       mTex = (MovieTexture)Resources.Load("Video/"+movieName);
          
       //set the AudioSource clip to be the same as the movie texture audio clip
       movieAS.clip = mTex.audioClip;
    
       //letterbox
       float newHeight = -(Screen.height-(Screen.width/(mTex.width/(float)mTex.height)));
       float yOffset = (-Screen.height-newHeight)/2;
       videoGUItex.pixelInset = new Rect(Screen.width/2, yOffset, 0, newHeight);
 #endif   
    }
 
    //On Script Start
    void Start()
    {
       StartCoroutine("SplashDisplay"); 
    }
    
    IEnumerator SplashDisplay()
     {
 #if UNITY_ANDROID
       iPhoneUtils.PlayMovie("Intro.mp4", Color.black);
 #else
       //set the videoGUItex.texture to be the same as mTex
       videoGUItex.texture = mTex;
       
       //Plays the movie
       mTex.Play();
       
       //plays the audio from the movie
       movieAS.Play(); 
 #endif
       yield return new WaitForSeconds(m_timer);
         
       Application.LoadLevel(m_loadLevel);
       
     }
 }

mp4 format give me some problems at the moment of the importation in Unity (Quicktime problems). So I convert my video in ogv then I import it in Unity and this works. But, this format is not suppoted on mobile. mp4 and 3gpp only on Android.

If someone already import and use a video on a mobile application, I'm willing him to explain how.
