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.

DVDs
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.
In addition, DVDs offer a variety of functions.

Terminology
Dolby Digital is a digital audio compression technology developed by
Dolby Laboratories that allows large quantities of audio data to be
efficiently recorded on discs. It is compatible with audio signals from
mono (1 channel) all the way up to 5.1-channel surround sound. The
signals for the different channels are completely independent, and since
the sound is high quality digital there is no loss of sound quality.
* The separately sold digital audio processor (PXA-H900, PXA-H701,
etc.) is required to enjoy full 5.1-channel surround sound.
The DVA-9861 performs Dolby Digital decoding when it outputs
analog audio signals; 2-channel audio, not 5.1-channel.
This is a home-use digital sound format of the DTS Sound System. This
is a high quality sound system, developed by Digital Theater Systems,
Inc. for use in movie theaters.
DTS has six independent sound tracks. The theatre presentation is fully
realized in the home, etc. DTS is the abbreviation for Digital Theater
System.
* To enjoy DTS surround sound you need the separately sold DTS
digital audio processor (PXA-H900, PXA-H701, etc.). The DVD
video software must also have a DTS sound track.
The DVA-9861 has a built-in DTS 2-channel audio decoder. Analog
audio outputs are available.
