Yes, CNET and majorgeek are both good. BTW, I am also interested in making vids of what my PC shows, like when I am playing aPC game, or running an application.
Well i have never done that, but presumably you would use your VGA or HDMI output to the camera? HDMI preferably because VGA doesn't carry audio signal (not that you cannot use VGA with a separate audio output).
I suppose their would be programs for capturing video on the computer, but i would bet they would be sun-of-a-bitch hard to use and then you have to deal with all the different formats and programs that are not compatible,,,, aaarrrrgg, just horrible, stick with the camera!
