About DVDs

Music CDs and DVDs have grooves (tracks) in which the digital data is
recorded. The data is represented as microscopic pits recorded into the
track these pits are read by a laser beam to play the disc. On DVDs, the
density of the tracks and pits is twice that of CDs, so DVDs can contain
more data in less space.

A 12 cm disc can contain one movie or about four hours of music.
In addition, DVDs provide sharp picture quality with vivid colours
thanks to a horizontal resolution of over 500 lines (compared to less
than 300 for VHS tape). With the addition of an optional, digital audio
processor (PXA-H900, PXA-H701, etc.), you can recreate the power
and presence of a movie theatre with Dolby Digital 5.1-channel
Surround.
