Most lilely some of the white lithium grease that they apply to the rails and
gears in the DVD player has came off and splattered across the disk and
possibly onto the lens. I have never personally seen this happen myself but if
the manufacturer of the drive had some employee or machine put too much on the
rails or in the wrong place , it could possibly happen. Too much grease is
not good.
