I am new to processing and have what seems to be a simple problem.  I am running a 2010 iMac with OS X 10.6.7 and Processing 1.5.1.  The Sony DFW-V500 connects using a Firewire 400 cable and I am using a FireWire 800 to 400 adapter. 

When connected, the camera's status indicator lights up green - meaning it is idle.  I am not able to select this camera in any of the system preferences, or even in iChat or photobooth.  The built in camera comes on every time. 

I assumed the following lines of code would provide me with the solution, but this was not the case. 

import processing.video.*;

Capture cam;

void setup() {
  size(640, 480);
  String[] devices = Capture.list();

  cam = new Capture(this, 320, 220, devices[1]);

  println(devices);

}

void draw() {
  if (cam.available() == true) {
    cam.read();
    image(cam, 160, 100);
  }
}

The list of devices reads:
[0] "DV Video"
[1] "IIDC FireWire Video"   (This should be it)
[2] "USB Video Class Video"


Any help is much appreciated.  Thanks!
