In most cases, poor video performance is related to display card or sound card properties. Hardware acceleration can cause problems on some systems, such as the disappearance of the mouse pointer when the video is playing, or fatal errors during lessons. Lowering
the hardware acceleration for the display card will often resolve these problems. Use Control Panel/Display to lower the acceleration setting. Note: do not lower hardware acceleration to “None.”
Poor multimedia performance is usually related to insufficient RAM. On workstations with 64 MB RAM audio/video performance may be sluggish. The video may be slow to draw to the screen and may stutter.
If video files are stored on a network, there may be additional performance issues related to your network configuration.
