I got to record my 1st BluRay disk on a Ma... Now.. How do I play it ? I am not talking about copy - protected disk but just my holiday movie. What software will play it (with menu etc). I can only see the files with VLC but i'd like to have a real BD player.

You're going to have to use bootcamp and watch it on the windows side. Apple has no BD support yet, because BD competes with their online movie store, er, I mean, because Steve Jobs says it's a "bag of hurt".

In reality, it's a licensing issue. DVD player software has licensing issues as well, but they're very cheap in comparison to BD.
