I have all the cables hooked in the back of the cpu but what software do I use??

I'm a bit confused on which way you're trying to go...

That is, are you trying to display OUTPUT to the TV? (Or are you trying to receive INPUT from the TV as to record a show?)

I'm trying to broadcast my TV to my ustream account but I cant

My cuzz said I need some kind of software to view TV on the monitor first

Well, displaying your computer images onto a TV is very simple, NO Software required, all you need is the proper cables, anyone at best buy can explain that to you, if your knowledge is limited.

Displaying from your TV to the internet now that is a complete different animal, you would need the new sets that have come out with web enable features,
