as far as the simple, 90's style skip fix kits, i doubt you will find them much anymore. there is so much on today's discs that a simple buffer solution will not be effective. your best bet is the Skip Doctor kit which Best Buy does sell in store and online. it is highly effective at repairing scratches on just about all discs. DVDs, CDs, and even video games! i wouldn't try it on Blu-ray though, i'm not sure how the cleaning compound would effect a bluu-ray laser's ability to read the disc.
