Can't play video with my webcam on.

Hello,

For my school project I need to create an exhibition. My exhibition is about spinal hernia. I want my visitors to see themself lifting up a box(a light one) in the correct way. If they lift it the wrong way they can go past a certain value. If they do, the sides will go red and a sound will play. After the sound I want my webcam to stop capturing and start playing a video with an animation showing how to lift the box the correct way. My problem here is that I can not get my video to work. Here is my code:

1. import processing.video.*;
2. import ddf.minim.*;
3. 
   
4. Capture cam;
5. Movie myMovie;
6. Minim minim;
7. AudioPlayer player;
8. 
   
9. int cx = 160, cy = 400, radius = 200;
10. color target = color(0, 0, 200);
11. 
    
12. PImage spiegel;
13. 
    
14. void setup() {
15. 
    
16.   size(1024, 680, P2D);
17.   cam = new Capture(this, width, height, 24);
18.   spiegel = createImage(width, height, RGB);
19.  
20.   minim = new Minim(this);
21.   player = minim.loadFile("Wrenched.wav", 512);
22.  
23.   myMovie = new Movie (this, "test.mov"); 
24. 
    
25. }
26. 
    
27. void draw() {
28.   if (cam.available()) {
29.     cam.read();
30.     image(cam, 0, 0);
31.     cam.loadPixels();
32.     for (int i = 0; i <cam.pixels.length; i++) {
33.       spiegel.pixels[i] = cam.pixels[cam.width + (cam.width*(i/cam.width)) - 1 - i%cam.width];
34.     }
35. 
    
36.     spiegel.updatePixels();
37.    
38.     image(spiegel, 0, 0);
39.     int drempel = 120;
40.     int loc;
41.     int teller = 0;
42.     int pixelDrempel = 10;
43.     noFill();
44. 
    
45. // 5 regels van @Alwin de Rooij
46.     for(int x=0; x<cam.width; x++) {
47.       for(int y=0; y<cam.height; y++) {
48.         loc = x + (y*cam.width);
49.         if(dist(red(cam.pixels[loc]), green(cam.pixels[loc]), blue(cam.pixels[loc]), red(target), green(target), blue(target)) < drempel) {
50.           if(dist(cx, cy, x, y) < radius/2) {
51.             teller++;
52.           }
53.         }
54.       }
55.     }
56.    
57.     rect(0, 0, 256, 680);
58.     rect(768, 0, 256, 680);
59.    
60.     myMovie.stop();
61.     if(teller > pixelDrempel){
62.       fill(255,0 ,0);
63.       rect(0, 0, 256, 680);
64.      
65.       player.play();
66.      
67.       myMovie.play();   
68.       image(myMovie, 0, 0);
69.     
70.     }
71.    
72.     if(teller > pixelDrempel){
73.       fill(255,0 ,0);
74.       rect(768, 0, 256, 680);
75.       player.play();
76.     }
77.    
78.     if(player.position() == 2630){
79.       player.rewind();
80.     }
81.     //player.position();
82.     //println(player.position());
83.        
84.   }
85. }
86. void movieEvent(Movie m){
87.   m.read();
88. }

If you move a blue object near the sides, the sides go red and you hear a sound. For 1 second you see a video pop up and then it stops. How can I get this to play?
