Digital video recorders (DVRs)--those mysterious black boxes with names such as TiVo, DirecTV DVR with TiVo, Sony Digital Network Recorder, UltimateTV and ReplayTV--have a devoted following for a reason: They let the viewer take control of the viewing. DVRs record TV programs onto a hard disk, rather than tape, so you can store, start, stop and erase them at the touch of a button.
