Using a Laptop as an Xbox Display
Generally, this is NOT possible. The video (S-Video, VGA) connections on laptops are OUTPUTS. They will not accept an in-bound signal. In order to get anything on the screen from an external source, you need a Video Input. It may be possible to connect an external Video Capture device to the laptop and use an composite or S-Video cable from the Xbox, but these connections are limited to 480i and the results may not be optimal in any case (i.e. - it may lag a bit, see below for more details).
