How can I play blu-rays on my computer?

Kevin bought a new Windows computer with a Blu-ray drive and he needs a player software. Leo advises Cyberlink PowerDVD, or WinDVD.

He's wondering if there's a way to play Blu-rays with VLC? If he can, then it's free. There's a good chance it's breaking the law to do so, though, so Leo recommends getting one of the paid programs and doing it right.
