There was once a detailed guide on how to copy DVDs on a Mac here. This is no longer complicated, so does not require a tutorial.
There are plenty of free and commercial software applications for this process. Here are a few for Mac OS X:
BD Regions - Check if a Blu-ray disc title is region free or not. Filter by region, letter, title or all of them together.
