Video preview software

I am trying to view my playstation 2 through my laptop screen.

I have recently bought a Dazzle DVC 100 video capture device which has given me the input I need from playstation 2 to laptop.

However the software that comes with it only allows me to preview the input signal in a tiny little box.

Does anyone know of any good free software that allows me to essentially preview the video from the dazzle device?

I have no need to record it, just to be able to preview it fullscreen,

I have windows vista and have already tried a program called captureflux which is what I need but keeps freezing every time I try to use it.

Thanks
