This question reminds me of one of my favorite computer questions: "Is a USB port serial or parallel?"
Well. USB stands for Universal Serial Bus.
And, DVR stands for Digital Video Recorder. (not analog)
A DVR is basically a VCR that uses a hard drive instead of video tapes. It can be used to record, save, and play back television programs. Unlike a VCR, however, a DVR can also pause live TV by recording the current show in real time. The user can choose to fast forward (often during commercials).
