Pc --> VGA --> laptop?

Hi

I need to capture video of one computer, with another laptop computer. All I can connect in the source computer, is the VGA. I wondered if anyone has experience with this.

I thought of using KD-VTCA3 VGA to Component Video Adapter (http://www.digitalconnection.com/Products/Video/kdvtca3.asp). But what could i use at the laptop for capturing the components?

and, would it work? could I get nice HD at the laptop without quality loss?

thanks very much for any thought
