Third, yes I have read here where a Blu-Ray renter recieved a disc that was scratched and would not play (if I find the post I'll put up a link to it). Bottom line, you may not be coming across scratches now, but a resistant coating is only that -- a resistant. Scratches can and will happen.
By the way, Blu-Ray discs do not use Durabis. They use their own coating.
Though I could not find the exact post I was referring to, someone here
had their Blu-Ray disc dropped on the floor which ended up getting scratched pretty badly after hitting a toy or two. The thread discusses a quote by the CEO Don Diotte of Venmill Industries (found in The Winnipeg Free Press, Page E5, Nov 15, 2006), which performs resurfacing and/or repairing of scratched DVDs, among other things:
"Blu-Ray may hold more data than HD-DVD disks, but there is a trade-off. To fit more information on the disk, Sony had to reduce the thickness of the protective coating. Consequently, the discs are much more vulnerable to scratches, if left lying around the table for example.... In the USA there's a billion dollar buy-sell industry around computer games. I do not know how they're going to face the reality that Blu-Ray is an unrepairable format."
He affirms that if Blu-Ray discs are not properly taken care of, they will end up getting scratched, which may prove to be a big problem for the disc owner. We don't know the long-term consequence of prolonged use of Blu-Ray media, but from doing a few searches you'll find that the discs do indeed scratch, even with the scratch resistant coating. And these are only from early adopters.
