Resolving a hardware conflict

for example, by installing a new graphics or audio card may impact performance. Some software changes may also impact playback performance (for example, downloading new drivers from the Web).

Before installing a new hardware or software component on your system, check for any potential conflicts between its 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 page 226.)

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.
