This is a little off-topic, but Blu-Ray is the antithesis of what Linux and FOSS is about. It seems that in order to use Blu-Ray on any *nix box is illegal.
Of course, the encryption scheme used on Blu-Ray has already been hacked. However, who wants to be considered a criminal by watching a LEGALLY purchased DVD on a Linux box with hacked Blu-Ray keys? Because that's what you'll be -- a criminal -- since to watch it on Linux you will have to use a hack.
Not only do they want to stop you from making LEGAL back-ups of your Blu-Ray's, but they want to control what platform you can watch it on (read: Blu-Ray loves M$ and wants to rule the world with them).
Blu-Ray will never be legal to watch on a Linux/Unix machine, even if you purchased the disk legally. Will this stop most people? No. but it's the principle of it, ya know. I, for one, will not be told what OS or DVD player I must use. Sorry.
