If this occurs, you will need to disable “hardware acceleration” on your PC. For Windows XP computers here’s how to do it:

  1. Right click on your Windows desktop.
  2. Select Properties in the pop-up menu.
  3. In the Display Property window click Settings, Advanced, Troubleshoot.
  4. Move the Hardware Acceleration slider to NONE.
  5. Click Apply.
  6. Click OK in the message box displayed by the video card.
  7. Click OK to exit

Most Vista/Win7 computers don’t offer this option. In this case try to use a DVD player that can play DVD’s without video acceleration. One popular program is the VLC media player (http://www.videolan.org/vlc/).
