TV Tuners on PC

[Commodore Larence]

So I am moving to a new house, and am going to be having a bit of a smaller room to do my gaming, and tv watching in. I am wanting to try to save a little space by running my PC and Cable TV all through the same monitor. I found where Tiger Direct has a 42" 1080p HD monitor for sale pretty cheap right now, and I am considering getting that and using it for my monitor. My PC currently does not have a TV tuner built into it, but it sounds like a pretty easy install, but I am wondering how well it works? Does any one reccomend a particular type or brand? How well do the USB plugin type cable connectors work? I wont be having a digital cable signal, just standard cable... And I am running Windows XP Media Center, I know it has a built in TV prgram in it, will that just auto-detect my TV tuner? Just curious on setting this up. I was going to just come out of my VGA output into the monitor, I dont have an S video output. Any help is appreciated.
