If you experience a problem playing DVDs, you may be able to fix 
the problem yourself. 

For general problems playing a DVD title, try the following steps:

Verify that the disc is in a format that the drive supports.

Ensure that the disc is properly inserted in the drive tray.

Ensure that the Display properties are not True Color (24-bit). 
If it is set to 24-bit color, there may be a video format error. To 
verify your display settings:

Click Start, Control Panel, Appearance and Themes, 
and double-click Display.

Click the Settings tab and ensure that the Color Palette is 
set to High Color (16-bit).

If it is not set to High Color, change the settings to 16-bit 
color and click OK.

Clean the disc and try again.

A dirty drive can also cause audio problems. If you have tried 
several discs and all fail, consider sending your drive to an 
authorized service provider to get it cleaned.

Verify that your computer recognizes your optical drive by 
double-clicking the My Computer icon on the desktop. The 
optical drive should appear in the list.

 for instructions 

on using Device Manager to view the optical drive properties. 

Check the Toshiba Web site for new information on optical 
drives and their operation.

Disable the Shut off Monitor feature in the Display Properties using 
the following steps:

Right-click in a blank area of the Windows

®

 desktop.

Click Properties.

Click the Screen Saver tab.

Deselect Shut off Monitor.
