How do I use VIVO?

[Cheesetogo]

I recently built my new computer about a month ago, with a evga 7800gtx. I was trying to use vivo today, but I don't know how to use it. I'm trying to play my gamecube through the vivo so I can play on my monitor. I hooked up my gamecube the vivo thing, and then plugged the vivo thing into the card. I then installed the program that came with the card for video editing and capture, but I can't figure out how to see the video that's coming in.
