Anyone Know What This Is and Why It Occurs?

Posted by Winston Smith on November 21, 2011 at 20:29:43:
When watching black and white old TV shows on DVD, if finely detailed black and white herringbone or checkerboard patterns occur (say in a character's jacket or dress), a most peculiar artifact occurs. The pattern suffers from a wavy purple and yellow oscillation effect over the material that has the pattern in it. (My teenage son laughs at this, calling it our TV's LSD experience.) :-)

The TV is a Pioneer 60" plasma 6010FD; the player is an Oppo BDP-83. It has done this for years, but I finally decided to ask: 1.) what is this called? 2.) why does this occur? 3.) what can be done to eliminate it?

Please pardon my ignorance of what effect is happening here. TIA for any assistance offered.
