DVD players have become increasingly popular and replaced the redundant VCRs and CD players. This revolution in video viewing is on account of the superior quality is has to offer. There is conspicuous difference between a movie viewed on a CD and DVD. DVDs are the thing of today. Both CDs and DVDs are optical storage devices and they look and operate in the same mannerism. The underlying difference lies in the format used to record. A standard DVD movie file occupies much more space than that of a CD. Since they occupy lot of space, it can be understood that DVDs have a much higher capacity than a CD. A single layer DVD offers 4.7GBs space and a double layered offers twice as much whereas a CD offers just 700MBs space.

DVD players are not only equipped to play DVDs but also CDs. In fact, DVD players can also play music. This becomes beneficial for those who don’t have stereo at home. As DVDs have higher capacity, it possible to store almost 14 times music than a CD. That means a collection of over 1500 songs inMP3/wma format in double layer DVD.

Differentiating between DVD players lies in their compatibility of playing various video formats. The latest technology based players can play DivX and windows media format along the avi and mpeg4 formats.

DVD recorders are also starting to come in but the market capture is still slow on account of its high price. DVD recorders can help us record our favourite television shows, movies or matches on DVDs which can be viewed as many times in future as liked. Most DVD recorders come with an in built hard disk or internal memory. This makes them compatible to record long hours of television footage in the memory. Since DVDs have become unimaginably reasonable, DVD recorders have an unlimited scope.
