Query: Works great .. unless you load the CD

Great picture quality and good face-tracking for the price. The problem starts when you try to follow instructions and load the CD and ... Oops! your system suddenly freezes. I have seen it everytime when I use a machine that has the "drivers" loaded. However, on other machine (using Windows native drivers) it works just fine.Pro's-------1. Value for money2.
