Microsoft announced at CEDIA that customers will now be able to add digital cable tuners with a CableCARD™ to any Windows® 7-based PC with Windows® Media Center. The Digital Cable Advisor tool is being provided by Microsoft to analyze consumer PCs to ensure that they are capable of a quality digital cable viewing experience.

The Digital Cable Advisor measures system parameters such as CPU speed, RAM, graphics card support for hardware acceleration, and digital connection capabilities. If the PC meets the minimum requirements, the tool enables digital cable functionality on the PC. Then, users can add a digital cable tuner with a CableCARD™. With a digital cable subscription from a TV service provider, users can access cable pay-TV, including premium content. This post describes the steps to assess and enable this experience on a Windows 7 PC.
