Play movie in full screen

Hello,

I have a video I exported into HD format .mp4. I am trying to call it using this code, however, it never shows in the game. The portion of this code that does work is the sound pausing part.

using UnityEngine;
using System.Collections;

public class IntroVideo : MonoBehaviour {
	//Variables
	public MovieTexture Video;
	
	// Use this for initialization
	void Start () {

	}
	
	// Update is called once per frame
	void OnGUI () {
		Video.Play();
		GUI.DrawTexture(new Rect(0,0,Screen.width,Screen.height),Video,ScaleMode.StretchToFill, false, 0.0f);
		if (Video.isPlaying)
		{
			audio.Stop();
		}
	}
}

I also had this problem a week ago… My problem was the movie itself… A .mov movie works well. So I am now avoiding .MP4
