Well, let's figure out exactly what you're wanting here. Are you wanting to actually use it for viewing and recording television? Because if that's your goal, it's not going to happen. ATI AIW cards are from the pre-DTV era, and have analog TV tuners. Everything has switched to pure digital transmissions. I'm not even aware of cable operators that are still sending out analog signals, though I'm sure some small-town cable companies probably still do.
If you're wanting to use this to record videotapes, then that's different. But before I get into that long explanation, let's see if it's even necessary.
So let me know what your intentions here are.
