Digital video recording (DVR) machines allow users to save televised content to an optical disk or hard drive for later viewing. DVR machines can be integrated with your cable service to add additional functionality such as scheduled recording and automatic updates. Comcast offers DVR machines for rental in some locations, so you can try out the technology without a large investment. You can add DVR to your Comcast service package in just a few minutes through a telephone call or Internet service request.
