SYMPTOMS

Consider the following scenario. You have a computer that is running Windows Vista Ultimate or Windows Vista Home Premium. The computer receives digital cable by using a CableCARD. However, when you watch Live TV or Recorded TV in Windows Media Center, you may experience macroblocking or blocking artifacts. For example, square sections of the picture are not displayed correctly. These sections may appear to be missing, or they may appear as a single block of color. Additionally, the picture may appear distorted or pixilated. If you rewind the video, the distortion appears again at the same location in the video.

This problem is most likely to occur when one of the following conditions is true:
  • You watch or record TV from a high definition (HD) channel.
  • The motion of images on the screen is very fast.
  • Scenes changes occur quickly.
