How do i add Video to GameObject?

I see plenty of examples for "adding" a video to things like UI, but when i try and change the code to apply such to a gameObject that i have created a tag for it gives me a bunch of errors.

I know you do not need a Pro license in U5 Personal, which is what I am using.

I tried to use the tutorial on here and frankly its not working right. I dragged one for playing video on a UI canvas RawImage to a cube and it worked but gave errors when play was started but still worked. I don't want errors obviously.

I tried to add this code so it works right but hey, that's the other "joy" I have had with this"Stuff."

Why wont this work?

using UnityEngine; using System.Collections;

public class PlayVideo : MonoBehaviour {

 public MovieTexture movie;
 private AudioSource audio; 

//this audio part keeps telling me its hidden and gives me stupid errors even when i change to public

 void Start () {
     GetComponent<ScreenTV>().texture = movie as MovieTexture;

//I made my own in Blender and named it and tagged it ScreenTV; It wont work either if i change this to GetGameObject.

     audio = GetComponent<AudioSource>();
     audio.clip = movie.audioClip;
     movie.Play();
     audio.Play();
 }
 
     void Update () {
     if(Input.GetKeyDown(KeyCode.Space) && movie.isPlaying)
     {
         movie.Pause();
     }
     else if (Input.GetKeyDown(KeyCode.Space) && !movie.isPlaying)
     {
         movie.Play();
     }

 }

}

Also when i tried to set this up so things will play one sample vid after the other it wont work, and if i hit the space_bar for one "object" i cant separate them out to play individually. They all play at once (with errors).

I been here already, and its "not working"
