In a list I belong to, someone posted about receiving a sealed Macgyver full series set as a present. It was gotten by someone off of Ebay. When the discs were inspected it was found that most of them had some degree of blotches on the DVD's. They have playback problems. I inquired more about them and pictures were posted and yes, it appears that the discs have small cloudy white patches (the pictures were sent to the list and are not available as links yet) that the owner seems to have trouble cleaning off. I am wondering if it is some type of mold. In this day and age, I doubt it's DVD rot, especially since many discs are affected. Has anyone ever had something similar happen? Does anybody have theories and possible solutions? I will try to post pictures later.
