I can't see how BluRay-media could be playing in real HD in an unmodified OS X-environment, as you need a layer of encryption, in order to be allowed to play the content you paid for. Apple had to add lots of intransparent DRM-layers into their OS, otherwise the content would be downsampled, so there's no reason to even buy Bluray media. I wouldn't touch it, due to the encryption. If I bought something, I'd expect it to work, no matter the OS I am using. as long as the content industry doesn't understand their real customers needs, I say let 'em rot in their own little world until they come to a customer-friendly agreement. That includes no (unskippable) "copying is evil. you are evil"-spots and sueing people who downloaded a few movies. Well... sorry for the OT, but you started it.
