Unity3D MovieTexture Loop

Actually I'm Creating an Intro cutscene in the Game I have created it and scripted it , But when the movie finishes the the movie loops and plays with laggy music.. any Ideas how to solve that, BTW. I have created another cutscene which have another Movie And it works perfectly when the duration finishes the movie ends and teleports into the other scene

----------

my code

 using UnityEngine;
 using System.Collections;
 
 [RequireComponent (typeof(AudioSource))]
 [RequireComponent (typeof(AudioListener))]
 public class MoviePlay : MonoBehaviour {
     public MovieTexture movie;
     
     private float _movieTimer;
     
     void OnGUI() {
         GUI.DrawTexture(new Rect(0,0, Screen.width, Screen.height), movie);
         movie.Play();
         
         if(Input.GetKeyUp(KeyCode.Space) || movie.duration <_movieTimer) {
             movie.Stop();
             Application.LoadLevel("Menu");
         }
     }
         
     void Update () {
             _movieTimer += Time.deltaTime;
     
     }
 }
