There is no Audio when playing an audio CD in the DVD drive

This is a very common problem, specially during new DVD drive installation.

DVD movie stops when my Computer returns from a screen saver

For example, if a screen saver starts while a DVD movie is playing, you will only hear the audio. When you try to return from the screen saver ( by moving the mouse, for example ) the player may stop playing the DVD movie entirely.

To recover from this problem, you may need to exit and restart the player applet ( such as Windows Media player ) This is typically related to a problem with operating systems like Windows XP, and you may be able to fix this problem by updating Windows from the Microsoft website. In the meantime, you should disable the screen saver through the Display Properties dialog box. In some cases, the movie player may have an option that will prevent a screen saver from running during DVD playback.

DVD drive not detected

There are several possible reasons why a DVD drive may not be detected. First check the power connector attached to the drive, and make sure that the drive is not being powered from a Y-splitter power cable. Next step is, check the signal cable. Both SCSI and EIDE/UDMA signal cables must be attached securely to the drive. SCSI interfaces are complicated a bit by termination, so verify that any SCSI bus is properly terminated. Make sure that the drive is jumpered properly for its SCSI ID or EIDE/UDMA master or slave relationship. Finally, make sure that the DVD drives are installed and running. Check the drives under the Sound,Video and Game Controllers (or CD-ROM) entry of your Device Manager.
