This one has drivers for XP, 2K, ME, and 98SE. I tried it out for a different application and it went back a few days later. Quality was not great, and it kept losing connection. It might have been a faulty unit, but I was thoroughly unimpressed.
Problem is, at least with a Lilliput, the button that switches inputs is momentary type of button and actually pressing it makes Lilliput cycle between 3 different signal inputs - VGA, video-in 1 and video-in 2. As far as I know Lilliput otherwise does not switch to "live" input automatically which makes things yet more complicated.
Any good webcam (USB 2 pref) comes with software that allows you to do just that, and it will run in a smallish window on the desktop normally 320x300 or so, then it saves it as an mpeg / avi etc to your hard drive as you drive, I plan on mounting at least 1 webcam on the exterior of the vehicle for track days etc
