Yes. Customers who want to use On Demand or the Comcast on-screen program guide will need a set-top box for any additional televisions.
If you have a TV with a CableCARD you will only be able to receive the digital cable channels and will not be able to receive On Demand, pay-per-view, or the on-screen program guide.
If you are a current Comcast customer and you want to know the price of an extra set-top box, chat with a Comcast representative or call 1-800-COMCAST. At this time, you cannot get an additioanl set-top box online.
