This may sound like a dumb question. But I have a computer with a "ViXS PureTV-U 48A3" tv-card. It comes with Windows Media Center. What exactly am I supposed to do in order to force this PC to output to my TV? Even though the device appears in Device Manager, neither Media Center nor the Display Properties seems to detect the TV as a 2nd monitor.
I have this card as well with Vista. I haven't been able to find any specs on it to prove it, but I believe this card doesn't output video at all, it just takes input, as it's a TV tuner card. If your PC has an S-video port, then you could output the video to a TV.
