Some (not all) purchased DVD's have been having a problem. The color goes from normal to red, similar to adjusting the color adjustment on the TV up. This is in cycles, as the color gets to red, the sound and video glitches and then starts over. I have not been able to determine any difference between a DVD that works and one that doesn't, the discs seem to have the same colors, etc. These are all new DVD's and not copies. All games have worked without a hitch.
