The TV Tuner will come with the software you need. Some come with actual remotes that you can use to change the channels. Also, the software they come with will usually have a TV Guide app and some sort of DVR function (like Tivo). You might want to do some research about them before you purchase one to see what you want in a TV Tuner. Some are digital, some are analog, etc. The better ones are digital. Just make sure it has the input that your cable uses (usually coaxial, unless you have HD service).
