<< thing is, how do you make it work? I have a gainward gf3 w/ vivo and i have a coaxial from cable. how can i get tv watching on my comp? I guess i need some kind of tv tuner thing that changes coaxial to composite video in. But then, where do i plug in the sound? >>
Well, you can do what xboxdude suggests in his original question:
"Can I use a VIVO card like the Gainward or MSI and see TV on a PC by feeding the svideo from a VCR?"
Just feed the video from your vcr into the video card. If your vcr doesn't have S-video, then use an S-video to rca adapter(my old Gainward GF2 Pro/450 came with one, so your Vivo gainward gf3 should have one) and connect it to your vcr using that.
To get sound just hook up the rca sound connectors from the vcr to your stereo, or use an adapter to connect it to the line in on your sound card.
