Precautions on writing/playing discs
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 on your writing software. For details about the setting
procedures, refer to your writing software documentation.
• Writing speed may be adjusted automatically according to the quality of the
disc used. Also, writing speed may be limited by the transfer rate of the
computer.
DVD region codes
The playback of DVD-Video (DVD discs) is protected and controlled by a
region code setting. For the drive to play back DVD-Video, the region code on
the DVD disc, the drive, and the DVD-Video playback software must be
identical.
With this drive, the region code can be set up to five times, including the initial
assignment (RPC phase 2
1)
standard). After setting the region code five times,
the setting becomes permanent and can no longer be changed. From this point
on, you are only able to play back DVD-Video whose region code matches the
one set at the fifth time.
Do not attempt to make unauthorized changes to the region code. Any
problems resulting from doing so are not covered by the warranty.
Hint
• You can change the region code of the drive on it's properties dialog box that is accessible
from the Device Manager.
• The DVDs created in stand-alone operation have the region code “All”.

Playing back DVD-Video
DVD-Video disc playback conditions are sometimes determined by software
manufacturers. Because the drive plays back discs as determined by software
manufacturers, some drive functions may not always perform as expected.
When playing back DVD-Video, refer to the documentation accompanying
each disc.
About copy protected DVDs
Most DVD-Video discs on the market are protected against unauthorized
copy. Attempting to copy protected discs violates copyright laws.
