VHS is good enough, why should I care about DVD

The primary advantages of DVD are video quality, surround sound, and extra features (see 1.2). In addition, DVD will not degrade with age or after many playings like videotape will (which is an advantage for parents with kids who watch Disney videos twice a week!). This is the same thing that makes CDs more collectable than cassette tapes. Did I mention video quality? The better your TV, the bigger the difference in picture quality between VHS and DVD.

If none of this matters to you, then VHS probably is good enough.
