Bianca said: What if my TV has PIP, and my cable box is dual tuner - is there a way to have a different channel on the computer than what is on the TV?

Few dual tuner cable boxes allow you to simultaneously tune and output two different shows at once. Typically, the second tuner is typically present to allow you to record something to the internal DVR while you watch something else - or record two different shows at the same time. (There are some Dish boxes that allow are designed with this ability in mind).

Whether or not you can do what you're hoping for will depend on the make, model, and feature set of your cable box. Keeping in line with clay's excellent explanation of this, could you hook up a second TV to your cable box now and get a different picture on both?

PiP on the TV really isn't a factor here. The limitation is the cable box, which can (most likely) only output one thing, even though it can tune two.
