|I agree that toothpaste is too abrasive. I tried it once and the disk went very cloudy. Just washing up liquid and warm water using your thumb to work from center to outside (not circling the disk) works fine. Rinse off with warm water and dry thoroughly with kitchen towel.|
Try copying the disk afterwards. Strangely I have found that sometimes works even when a disk doesn't play.
As given in #1 make sure it is not your DVD player that is at fault.
Always pop back and let us know the outcome - thanks
