Transcript: Buy a Digital Video Recorder, or DVR

Whether you're working late, on vacation, or just out on the town, with today's digital video recording technology, there's no reason to miss your favorite TV shows.
 

What is a Digital Video Recorder or DVR?

Digital video recording or DVR enables you to record, pause, slow down, and even rewind, it's live TV. No need to endure anymore annoying commercials! Unlike the analog format you use with your VCR, a DVR records digital video and stores your shows on a hard drive instead of a tape. The hard drive comes in different sizes, the larger the drive, the more shows you can record, and the more you can record at a higher quality than the standard VCR.
 

How Much TV Can I Record on a DVR?

Generally, one gigabyte equals one hour of programming. So make sure you buy the size that fits your needs. DVRs also include some type of programming guide that allows you to choose what shows you want to record, up to several days in advance. If your two favorite shows are on at the same time, don't panic, new DVRs have the ability to record one channel while you watch another. Some will also allow you to record two programs at the same time.

Comparison Shopping to Buy a DVR

The two most recognizable brands are TiVo and ReplayTV.

Both are separate boxes that hook up to your TV like a VCR. A monthly subscription will enable you to download information for your programming guide through a phone jack or the Internet. Both TiVo and ReplayTV work with cable or satellite.

So, which is better? Well, it depends on what features are most important to you. TiVo has been praised for its simple interface and easy scheduling while ReplayTV is the choice for power users who will appreciate the progressive scan and wireless capabilities.
 

Other Options for Buying a DVR

If you don't want to fork over the cash for a set top unit, contact your cable company or satellite dish provider as they too may offer a DVR with many of the same features. Some DVRs even have built-in DVD recorders, which allow you to not only record your favorite shows, but also save them forever by burning them onto a DVD.

Whether you decide on TiVo, ReplayTV or your cable provider's service, expect to be wowed by digital video recording. It'll put 'YOU' in control of your TV viewing like never before.
