DVR, or digital video recorders, are becoming increasingly common in the home. They record all your favorite programming, and save it for you to watch at your convenience, without the hassle of setting up videotapes of DVDs to record. Instead the information is stored on a hard drive, much like the files on a computer. Understanding how to use DVR, and what types of DVR are available can make every consumer more prepared to get the most out of their home theater system.
