I have a sony vaio laptop with a nvidia 64 meg ddr graphics card with a/v out. I am wondering if there is any way that i can get a tv tuner card through my card slot (or firewire). I want a tv tuner card that has preferably coaxial ends and s-video. (coaxial so that I can hook up bunny ears and watch some tv on the road). Is this possible or do i have to get a new graphics card or what???
