begin video

I can't find reference to beginVideo() despite what the example in Learning says.
I have my "Creative" web-cam plugged into the usb port.
I run the code below:
Code:
boolean newFrame = false;
void setup() {
size(320, 240);
beginVideo(width, height, 4);
}
void videoEvent() {
newFrame = true;
}
void loop() {
if(newFrame) {
background(video);
newFrame = false;
}
}

And that's when my computer locks up. I've waited quarter of an hour with no change other that the screen saver kicking in and I have to reset the computer or wait fifteen minutes for the task manager to shut down Processing. My computer only seems to slow down when I have in excess of 10,000 basic objects running around so I don't think it's a speed issue.
I'm assuming there's something I haven't done but there's no indication anywhere of what. All the examples I've seen seem to infer a magical detection of the web-cam. I've tried quick-time and that's not a problem.

Thanks. I may be lacking the correct driver, am going to start rooting. The command beginVideo() crashes the computer regardless of a web-cam. No exceptions thrown. I imagine I should wrap it in a try{}, but unsure if that works at setup(), and since there is no exception reported that's unlikely to work.
No offense personally but I hate your computer. It plays havoc with my website CSS, won't pass my javascript remote activated flash movies, saves web pages in a foriegn format that is unreadable on PCs and OS 9 doesn't like my PHP counter program. Make's demonstrating at school a pain. Damn you Apple.
Update: winVDIG has solved the crashing of my computer. It seems that when Processing searches for the components it locks everything up and doesn't stop looking. Now I have a problem getting it to differentiate between the video card and the web-cam. I will raise this question in "cameras". Thanks for your time.
