If your favorite DVD is scratched and does not want to play anymore - do not worry ahead of time. Of course, if the scratches are very deep and corrupted themselves data on the disc - there is likely nothing to be done. But if the damage affected only the upper protective layer, then deal with this problem - a piece of cake. Rub the scratched disc banana peel, and wax contained in it will help get rid of small scratches. Rinse with water, dry - voila!
