If you have a compatible* DVR set-top box connected to your Control Center, you'll also be able to search for and launch your saved DVR content using Control Center's search functionality. Any search performed with your Control Center's remote will also search your DVR content, and any results will appear in its own section:
The search results are organized into categories in the section shown above, and if there are results in your saved DVR content, the DVR option will appear here.
*Control Center currently supports DVR searching for Xfinity, DirecTV, Dish, and TiVo DVRs. Content will not automatically launch on FiOS and Spectrum DVRs.
