The advent of DVD movies marked a dramatic change in the at-home movie-watching
experience. Smaller than traditional VHS tapes, DVD (or Digital Versatile
Disc) films are trendy, easy to use, and fun to watch. DVDs look a lot like
audio CDs, but they incorporate both audio and video components.
DVD movies offer a lot to viewers, including double the vertical resolution
of VHS tapes if you have a display capable of registering the improvement.
DVDs also provide digital sound, which some listeners prefer to analog sound.
Perhaps the biggest advantage to DVD movies is the amount of information
that can be stored on a single disk. While high-quality VHS recordings tend
to be limited to a few hours of footage, DVD movies, particularly two-sided
ones, can be much longer. In fact, most DVD movies offer much more than
a film. Added features such as blooper clips, actor profiles, behind-the-scenes
footage, interviews and games are commonly packaged on the same disk as
the featured film. DVDs also allow movies to be presented in several languages,
or with sub-titles.
For those of you who don't have time to watch a whole story at one time,
DVD movies are broken into scene segments so it is easy to find where you
left off, or to go back and re-watch a particular section. This feature
can be especially useful if you have children, or if you are interrupted
On a physical level, DVD movies are made of a single component, one disk
that spins inside your DVD player. When compared to the many plastic parts
of a VHS tape, this one-part design makes it less likely your movie will
be damaged. Care should still be taken, however, to avoid scratching the
surfaces of your DVD movies, as even a small scratch can affect a lot of
data on the disk.
