well ridv34, technically its a computer application, software, so he did post in the right place. and yeah just go on newegg and buy like a 30$ tv tuner card and thats all you should need.
seems like it will fit your needs, as long as you already have a cable which you can connect.
that thing you posted, though, isnt quite what it seems to be. go to http://www.radioandtelly.co.uk/internet.html and check their review of it at the bottom of the page to see what it actually is.
