Can i use ATI or Nvidia without one of their video cards?

Several Questions

I have an HP pavilion ze4230, bought brand new, but i am having extreme difficulty trying to find information on the video card, brand and that sorta thing. I know it has a radeon IGP 340m adapter. Is that the video card, if not, what is?

Do i need a different video card to have movies play on the TV using a S-video cable through the laptop? I get the desktop and windows to show on the screen, but no movies or videos.

What are the drivers i need to get it working, and which would be better for this situation, ATI or Nvidia?

Thanks

i tried ati catalyst and my window shrunk on my laptop and the properties for the drivers don't register. Is that normal?
