If Something Goes Wrong
WinDVD problems
WinDVD performance decreases after making a system
change.
DVD playback performance is dependent upon several
system resources. 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 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 the following:
1 Close any other open applications to improve the
performance of the DVD playback.
2 Ensure DMA is turned on. For more information, see
"General issues" on page
3 Make sure 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.
