>What about the anti-piracy measures on the Blu Ray?

In the US, bypassing DRM is a crime even if the intended use is legal. There are exceptions for things like criticism and accessibility, but I don't believe they'd be relevant.

Maybe it'd be as simple as selling your new copies as "for review purposes" and it'd be legal, I'm not sure.

The ban on bypassing DRM only applies to copyright protection measures, and if a work is in the public domain there is no copyright protection on it. It does unambiguously affect fair use of copyrighted works, but just dumping fully-PD works that happen to reside on DRM-protected media ought to be OK.

It had been a while since I read the DMCA, and I was mistaken. It says "No person shall circumvent a technological measure that effectively controls access to a work protected under (copyright)" so it doesn't need an exemption.
