What is the difference between a DVR and VCR?
DVRs store content in a compressed digital format onto a hard disk drive (like a computer), which alleviates storage limitations of VCR tapes. VCRs use VHS or Beta tapes to store information in an analog format. VCR tapes can only capture up to six hours of programming while a DVR can store between 30 and 50 hours. DVRs also provide more sophisticated recording options. For example, it can be programmed to record an entire season of your favorite show.
