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 21) 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”.

1) Region Playback Control (RPC) standard.

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.
