DVD stands for Digital Versatile Disc. It is a high quality optical format
that doesn't degrade every time you use it. In fact, DVD video quality is
twice as good as VHS tape quality.
DVD players have become household items in the Western world and by now replaced traditional video recorders. Many people have portable DVD players as well. Portable DVD players are compact units which include both the DVD player itself and a small screen. Size of the screen in a portable DVD player can be anything from 2.5" to 12". These units are light in weight and often come with handy cases to carry around.

Quick DVD Players Shopping Tips
Video Outputs - Virtually all DVD players offer a choice of video
outputs; most important is making sure the DVD player you buy will
be a good fit with your TV. Composite video (with a yellow-colored
RCA jack) and S-video connections are a given on most DVD players,
but some also provide component-video outputs, suitable for higher-end
TVs. Component-video outputs separate the luminance (brightness),
red, and blue signals, resulting in pictures with superior contrast
levels and more faithful color reproduction. Progressive-scan outputs
are special component-video connections designed for use with high-definition
and HD-ready TVs. These provide a superior, "filmlike"
picture by scanning from top to bottom in one fluid pass, making
it harder to discern a picture's individual scan lines, which increases
resolution while minimizing distortion and flickering.
Digital Audio Outputs - These outputs enable you to connect the
DVD player to an audio-video receiver with Digital Theater Systems
(DTS) and Dolby Digital processors, which decode the DVD's digital-audio
tracks--including discs encoded in 5.1-channel surround sound. Look
for players with both optical (fiber-optic) and coaxial (75-ohm)
digital outputs; this will give you more options for enjoying music
and movies through your home entertainment system. If you're buying
a DVD-audio player, make sure your receiver will accommodate 5.1-channel
analog outputs, since most DVD-audio players don't pass the high-resolution
DVD-audio signal digitally.
Surround Formats - Virtually all DVD players are capable of outputting
Dolby Digital 5.1-channel surround sound. Although nearly all of
today's DVDs are encoded in Dolby Digital, there's an expanding
list of DVD and CD titles available in 5.1-channel DTS (Digital
Theater Systems), which uses less compression and is generally considered
to be a superior-sounding format. If you're interested in enjoying
DTS-encoded discs, you'll need a DTS receiver, or you'll need a
DVD player with a built-in DTS processor that can be mated with
a compatible receiver. If DTS is important to you, be aware that
some budget DVD players have difficulty passing the 5.1-channel
signal onto DTS-compatible receivers. If DTS is not important to
you, most of today's Dolby Digital-only budget DVD players are reliable.
Disc Capacity- Models range from single-disc machines to 2-disc,
3-disc, 5-disc, and 6-disc players to mega changers that can hold
up to 301 DVDs. If you're planning to use the player for music listening
and you like to play several hours' worth of music at a time, you
might consider purchasing a multidisc machine. The 5-disc and 6-disc
models use traditional carousel platters to load DVDs and CDs, while
the 3-disc variety uses either a carousel or sliding-drawer mechanism.
Screen Dimmer and Video Bit-Rate Meter- Neither of these features
will enhance a DVD player's performance, but both are very cool.
Players that allow you to dim or turn off the front-panel display
are preferable, because bright LCDs are distracting in the dark.
Bit-rate displays, which appear either on the TV screen or on the
player's front panel, reveal how much MPEG-2 compression is being
used from scene to scene, with higher numbers representing a larger
bit-rate allocation and lower numbers indicating a lot of compression.
Action sequences, for example, will typically measure 8 to 9.5,
while highly compressed, static scenes often dip below 2.
