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).

applications and/or changes to your system hardware, 
software or configuration can impact playback performance.

Closing any other open applications to improve the 
performance of the DVD playback.

performance.
