the region code has been changed from its initial setting four times, it is fixed and can no longer be changed. To change the region code, you must have a DVD with the new region-code settings

To display the region-code status, follow these instructions:

1.In the WinDVD window, click DVD Options.

2.Click DVD Region.

Care and maintenance

This section includes information on taking care of your CD-RW/DVD-ROM Combination Drive and the CDs and DVDs that you use with the drive.

Caring for a CD or DVD

Digital discs are high-density media that must be handled with care and kept clean to ensure that they remain readable. The following precautions help to prolong the life of your discs.

Attention: Wiping a disc using a circular motion can damage the disc and cause data loss.

vHandle the disc by the edges or the center hole. Do not touch the surface of the disc.

vTo remove dust or fingerprints, wipe the disc from the center to the edge with a soft, lint-free cloth.

vDo not write on the surface.

vDo not place the disc in direct sunlight.

vDo not use commercial cleaners to clean the disc.

vDo not bend the disc.

Caring for the CD-RW / DVD-ROM Combination Drive
