If we can factor N it doesn't necessarily mean RSA is broken. It doesn't mean BD+ is broken because it would still require the aes device keys and a way to perfectly emulate a licensed player but it would have lost some of it's strength though. And it certainly doesn't mean the end of public key cryptography.
The knowledge of the private key of the BD+ license administration is not necessary to repair every (future) BD+ damaged movie. I try to evaluate the strength of this RSA keysize (1280) using the latest mathematical advances out of my personal interest.
