Topic: I cannot play a DVD.
If a region code warning appears when you are using the DVD player application,
it may be that the region code of the DVD you are trying to play is incompatible
with the region code setting of your optical drive. A region code is listed on the
disc packaging. Region code indicators such as “1” or “ALL” are labeled on
some DVDs to indicate the type of player that can play the disc. Unless a “1” or
“ALL” appears on the DVD or on its packaging, you cannot play the disc on this
system.
If you hear audio but cannot see video, your computer’s video resolution may be
set too high. To improve video resolution, verify that your screen area is set to
1024 x 768, using 32-bit color (preset factory default). To check your video
resolution, see the Troubleshooting topic, “How do I change the video resolution
of my display?.”
If you see video but cannot hear audio, check all of the following:
❑ Verify that your DVD player’s mute feature is turned off.
❑ Check the master volume setting in the Audio Mixer.
❑ Check the volume settings on your computer speakers.
❑ Check the connections between your speakers and the computer.
❑ Verify that drivers are installed properly, by following these steps:
1 Click Start in the Windows taskbar, then select Control Panel.
2 Click Performance and Maintenance and then click Systems. The
System Properties dialog box appears.
3 Select the Hardware tab and then select the Device Manager button to
view installed drivers.
A dirty or damaged disc may also cause the computer to stop responding while it
tries to read the disc. If necessary, remove the disc and check that it is not dirty or
damaged.

If your computer’s video memory (RAM) is 11 MB shared system memory, you may
improve video resolution by changing your screen area to 800 x 600, using 16-bit
color. See your Specifications sheet for details about your computer’s video RAM.
