you can go to almost any video store or some pawn shops, will resurface, any disks, for about $1.00 for small scratches to $3.00 for bigger scratches, a heads up if you have problems with scratches on your cd"dvd"s blu-ray"s you could invest in to some d-skins
From what I've been told by a shop that resurfaces discs, Blurays are pretty much impossible to fix. This is due to the supposed scratch-resistant coating. Removing this coating results in ruining the disc. CDs, DVDs, HD DVDs, and game discs usually can be resurfaced.
