I have been looking at a few youtube clips of people delaminating (destroying) DVD's and CD's. Man people are idiots. 20 seems high. Just be careful about misdiagnosis. I had Jigsaw on bluray skip in 2 players. Swore it was the disc. Then it played just fine in a 3rd player. That proves it was not the disc but a firmware issue (others have also proven this). I have a few DVD's that play on one or the other players...etc. DVD's are old tech anyway and were made really really cheap. Sad the MOD mentality seems to want to bring that back. At least the indelendent companies know quality and I am happy to pay the difference. Thankfully in your case you can just go buy another. Quality has always been an issue in almost in business at one point or another. Good disc mamufacturing can and does live lifetimes. I have some CD's that are approaching 35 years old without issue at all (ripped several just last week).
