When subscribing to Comcast digital cable, you must have the digital receiver connected directly to your TV. This is required because it unscrambles the high-tier programming stations (such as HBO and Cinemax). The receiver also contains the provided DVR. Although a service technician can hook up the equipment, it may cost you extra, and you’ll have to wait for the installer to come to your home. Thus, knowing how to set up the receiver to your own television is essential.
