Digital Versatile Disc that holds vi deo. DVD video discs have adopted
“MPEG2”, one of the world standards of digital compression technologies. The
picture data is compressed by 1/40 on average and stored. Variable rate
encoding technology in which the volume of data assigned to the picture is
changed depending on the picture format has also been adopted. Audio data is
stored using PCM and Dolby digital, whic h enables higher quality of sound. Fur-
thermore, multi-angle and multi-language features will also help you enjoy the
more advanced technology of DVD video.

• CD-R or CD-RW playback may not be po ssible in some instances, depend-
ing on the characteristics of the disc.
• There is a wide variety of freeware and other encoding software for MP3 and WMA files on the market, and depending on the status of the encoding and
the file format, poor sound quality or noise at the start of playback may result.
In some cases, playback ma y not be possible at all.
• When files other than MP3 or WMA files are recorded on a disc, it may take more time to recognize the disc and in some cases, playback may not be pos-
sible at all.
• Microsoft, Windows, and Windows Medi a are the registered trademarks of
Microsoft Corporation in the U.S. and other countries.

process that allows discs to be played on a conventional CD player) cannot be
played.
●It may not be possible to play CD-R /CD-RW discs recorded on a music CD
recorder or a personal computer because of disc characteristics, scratches or

CAUTION
■DVD video precaution
Conversational speech on some DVDs is recorded at a low volume to emphasize
the impact of sound effects. If you adjust the volume assuming that the conversa-
tions represent the maximum volume level that the DVD will play, you may be star-
tled by louder sound effects or when you change to a different audio source.
Loud sounds may have a significant impact on the human body or pose a driving
hazard. Keep this in mind when you adjust the volume.
