What programs are compatible with Dazzle DVC 100?

Well, I use my dazzle for recording video gameplay. But I lost my installation cd i had and I want to use my dazzle on my other computer... I know obviously that pinnacle studio allows you to record with it... and windows movie maker for XP... But I got windows 7 and I want a program thats free and allows me to record video gameplay/audio... and for me to record voice for commentary over my gampelay. THANKS
