Real time viewing w/ a capture device (playing videogames)

[CMP1223]

I have a video capture device that captures video from stereo RCA jacks and composite video at 320x288 into a USB, and was wondering if i can play video games through it. It capture video in real time uncompressed AVI, and it is VFW compatible. Is there a software that will allow me to hook up the outputs on my console and view it on my computer? I don't need to store the video, just play the gameon my computer! If not, what kind of device would do this?

Thanks
Chris
