214 If Something Goes Wrong
Resolving a hardware conflict

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 page213.)
3If you have installed new hardware (such as a new graphics
card or audio card), ensure the component’s drivers support
Microsoft® DirectX® 8.1 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.

WinDVD will not function properly with “debug” software

installed.

The WinDVD application will not function properly if it detects
that debug software is present on the system. Remove the debug
software to restore functionality of WinDVD.
