Mac OS X: DVD Player Distortion or Discoloring at Edge of Frame

With some DVD-Video discs you may notice a narrow distortion or discoloring at the left or right edge of the picture.
Symptom

A narrow distortion or discoloration ("encoding artifact") appears at the left or right edge of the picture. For example, you may see a faint green line on the right side, or a thin, blurred line during motion.

Products Affected
Solution

This is expected behavior because Apple DVD Player displays the entire video frame. The same issue can occur with a set-top DVD player that is connected to a television set that shows the entire picture. Many television sets "overscan" the video so that the outermost edges of the picture are not visible.
