Precautions when Writing Data to Disc
Write speed and compatible discs
• When writing data to disc at high speeds, you must use the appropriate type
of disc.
• Configure the writing speed through your writing software. For details about
the setting procedures, refer to your writing software documentation.
• When writing data to disc, the drive may adjust the writing speed to the
quality of the disc in the drive. Depending on the transfer rate, there may also
be limitations on writing speeds.
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 region code of the drive, and the region code of the
DVD-Video software must all match.
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 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 accessible from the
Device Manager.
Precautions when 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.
DVD copy protection technology
Most DVD-Video discs on the market are protected against unauthorized
copy. Attempting to copy protected discs violates copyright laws.
