Precautions On Writing/Playing Discs - Sony VRD-VC30 Operating Instructions Manual

About playback/reading compatibility
CD-R and CD-RW discs created with the DVDirect can be read on most CD-
ROM drives. However, some older CD-ROM drives cannot read CD-RW
discs.
In addition, CD-R music discs created and finalized with the DVDirect can be
played on most CD players, but there are some CD players and automobile CD
players that do not support or guarantee playback of CD-R discs.
Because of the differences in quality and characteristics between various CD-
ROM drive, CD player, CD-R disc, and CD-RW disc manufacturers, playback
may not be possible depending on the combination.*
DVD-Video discs created and finalized with the DVDirect can be played back
on most standard DVD players. In addition, DVD-ROM discs created and
finalized with the DVDirect can be played back on almost all DVD drives.
However, depending on the combination of the type of player/drive and the
disc, playback/reading may not be supported or possible. For example, some
drives do not support multi-session/multi-border DVD-ROM discs. In such
cases, the drive may only read the first session/border of the disc.
Further, because of the differences in quality and characteristics between
various DVD drive, DVD player, and disc manufacturers, playback/reading
may not be possible depending on the combination.
*Playback compatibility is not under warranty.

Write speed and compatible discs
• When writing data to disc at high speeds, you must use the appropriate type
of disc.
• Set the writing speed with your writing software. For details on configuring
the setting, refer to your writing software documentation.
• Writing speed may be adjusted automatically depending on the quality of the
disc used. In addition, writing speed may be limited by the transfer rate of
the computer, or the DVDirect may limit writing speed to preserve a good
reading quality.
DVD region codes
The playback of DVD-Video (DVD discs) is protected and controlled by a
region code setting. To use the DVDirect to play back DVD-Video on your
