This is my problem. I've tried looking on a few different library blogs and I've tried some different Google searches, but I haven't found anything:
I often come across a DVD that is fairly scratched up. I want to know whether to put that DVD back on the shelf or send it to be repaired or withdrawn. However, I want to do that without playing the entire DVD in order to see how much damage the scratches actually represent. Does anyone know if there is a way to tell by looking at a DVD if it is sufficiently damaged not to play well, or at least to make an educated guess?
