236 Appendix B Computer Issues
Display Drivers and DirectX If you run into display problems or system errors, it’s often a good idea to look
for an updated display driver, either from the card’s manufacturer or the
chipset manufacturer (i.e., ATI/AMD or nVidia). WATCHOUT also requires
DirectX 9 or later – a standard part of Window Vista. You can download the
latest version of DirectX from:
http://www.microsoft.com/directx
OTHER ISSUES This section lists some other issues known to cause problems from time to time.
Video Playback Some DVD player programs – often included with graphics cards or DVD
drives – may interfere with the ability of WATCHOUT to play back video
content (including some related audio formats). To solve this problem, uninstall
the DVD player application and all its components.
Sound Playback You need to install the proper software driver for the sound card installed in
your computer. The driver received with your computer, operating system or
sound card is usually sufficient, but you should check the sound card manufac-
turer’s web site to make sure you have the latest driver version installed –
particularly if you’re experiencing sound playback-related problems.
When installing or updating sound card driver software, avoid installing other
associated software. Additional software is often provided that will run as
background applications. You may have to check for and remove such soft-
ware after installing/upgrading sound card drivers (see “Removing Back-
ground Programs” on page 231).
