Playback of QuickTime .mov files is very erratic on my system Macbook Pro OS X 10.6.5. Sometimes the movie plays perfectly sometimes it just quits and I get an error about a pointer or other errors. Here's my code:

import processing.video.*;
Movie myMovie;

void setup() {
  size(640, 480, P2D);
  myMovie = new Movie(this, "drb02.mov");
  myMovie.loop();
}

// Called every time a new frame is available to read
void movieEvent(Movie myMovie) {
  myMovie.read();
}

void draw() {
  image(myMovie, 160, 120, 320, 240);
}

Is there something wrong with my code?

Thanks,

George
