Geforce GTS/ATI All-in-Wonder compatibility

[Wheeler]

For X-mas I got a ATI All in wonder 128 PCI card. I didn't do the proper research on the product and just told someone to get it for me. I wanted it to hook my cammcorder to and watch the video on my monitor and to take vid caps from DVD's if possible. But here's the problem that I never thought of. I already have a Nvidia Geforce card that is AGP. I thought the ATI would just hook in and I could just plug my cammcorder into it. Well eveidently its supposed to replace my Geforce, not just be a separate card. So is there any other option besides buying another monitor?

Thanks for all the help
