• Problem : An optical medium, such as a CD, DVD, or CD-RW disc cannot be read.
Solution : Make sure that the CD, DVD, or CD-RW disc is not dirty. If it is, clean it with a cleaner kit.
Test another CD, DVD, or CD-RW disc. If the computer can read the other disc, the first disc might be
defective.
Make sure that the disc is loaded on the center pivot of the drive with the label side up. (You should
hear a click.)
Make sure that the disc is in one of the following formats:
– Music CD
– CD-ROM or CD-ROM XA
– Multisession photo CD
– Video CD
– DVD-ROM (DVD-video)
• Problem : The computer cannot play a CD, or the sound quality is not good.
Solution : Ensure that the disc meets the standards for your country. Usually, a disc that meets the local
standards is marked with a CD logo on the label. If you use a disc that does not meet these standards, we
cannot guarantee that it will play, or that, if it does play, the sound quality will be good.
• Problem : The HD DVD tab in the WinDVD8 program is dimmed and I cannot use it.
Solution : Your computer does not support an HD DVD drive.
