I deliberately scratched DVD (whose title I do not like) by sanding it with fine sandpaper.
on my dvd player that plays well yet scratched discs this time it was written "Amount defect record."
bistros of the day skip doctor I go to disk once and I have a beat and the film works perfectly.
I highly recommend this product
in the instructions it says Kit disc and after 25 to buy a kit that costs about ten euro
