save webcam from msn

is there any way to save what you see on someone else's webcam on msn to a file (pref avi or mpeg), or any software that does this for you?

thanks in advance :)

take a look there, i used it once, its not too bad cause it lets you either capture the full screen, or just a specific area (such as the msn webcam window)

this seems nice, but it does mean that i have to have that msn window in front all the time.......

does anyone know a program that will allow me to record it even if im surfing or something (something that will capture the incoming data stream)
