Sometimes DVDs and compact discs don’t want to work. This is due to a film that has somehow gotten on the surface. To quickly get rid of this take some liquid dish-washing soap, pour it on the surface run it under water. Moving the soap around the disc in a circle. Once you have the disc covered rinse it off.
You want to take a clean towel, than wiping it from the center and out to the edge. Do this around the whole disc. You don’t want to dry it in a circular motion due to the thin aluminum film will tear and your Cd’s and movies will be ruined.
