Help with VIVO

Now that I have VIVO on my x800xt-pe, I was wondering how do I use it? Video out is easy enough to work out to a tv, but how do you use the video in?? Do i need software of some sort?? Please help, its bugging me and would love to be able to hook up my ps2 or camera to it.

Thanks.

You need to install ATI's MultiMedia Center (MMC).
