I have trouble with paper labels causing my DVDs to freeze and distort. After a little research this turns out not to be uncommon. After removing the label from one disc the problem disappeared. Most of the label came off OK but some places it left the glue layer with thin paper. I managed to remove it all with my thumb nail and a rag with paint thinner, being careful to keep it on the label side.
I have 30 more to go, any suggestions for better removal?
