resource requirements and your current system configuration.
Also, if you change your operating system, check with your
PC manufacturer or your graphics card vendor to ensure that
you have the appropriate drivers for both your hardware (for
example, the graphics card) and software (drivers must
support the operating system and DVD with WinDVD).

Slow playback performance.

DVD playback is a resource intensive application. Other
applications and/or changes to your system hardware,
software or configuration can impact playback performance.
If playback is slower than normal, try:
1Closing any other open applications to improve the
performance of the DVD playback.
2Ensuring DMA is turned on. (See “Playback performance
is poor.” on page197.)
3If you have installed new hardware (such as a new
graphics card or audio card), ensure the component’s
drivers support Microsoft® DirectX® 5.2b or higher and
WinDVD. Contact the manufacturer of the component.
4Verifying that your display driver resolution, color depth
and refresh rate are optimal for DVD playback. (Some
systems do not support video overlays if these parameters
are not optimal.) Try lowering these settings to improve
performance.
WinDVD problems: Content issues

Movies exhibit poor performance of “Director's

Commentary” or other similar optional content

versions.

Some movies may exhibit poor performance of these
features. In particular, the video portion of the movie may
become jerky or show pauses. The normal version of the
movie will not show this problem.
