2 Video cards?

Is it possible to run 2 video cards on XP?

One card is an AGP and the other is a PCI TV turner card.

I've been watching movies on my tv that play from my PC using the S-Vid out. They look perfect, but I wanted to add the tv card.
Any suggestions before I install it?

I can't imagine any reason why you wouldn't be able to do that. It might get a bit complicated but I doubt it will be too difficult. Try it and see what happens :)
