Blu-ray Suffering From Disc Rot?

There is an on-going thread over at the AVS Forum from a user suffering with disc rot on his BR copy of The Prestige. It turns out that half the people in the thread are also suffering from the same problem with the same movie. It doesn’t always deem the movie unviewable, but more often than not it does. If you own any BR discs, especially that movie, you may want to look at the back and see if your disc has the malady as well.

This looks like the issue with the hardcoat application as it is spread thruout the disk. Maybe the hardcoat process got contaminated with something during a particular batch.
