I use an ATI tv wonder pro PCI card to watch tv. I use the Multimedia Center software that came with it, but its pretty lousy. I'm not entirely sure why. The picture is bad, sometimes it freezes up. Its just all around bad. There may be a conflict with my NVidia GeFOrce MX AGP. I don't know. I would like to find some other third party TV viewing software that is compatible with my system. I hope there is some good free-ware out there to be found.
