you have three Blu-ray Regions. A, B & C
these can either be locked to a specfic region (A for example) or they can be locked to multiple regions (A,B or A,C or B,C)
the term region free means that they are encoded regions A,B & C
the packaging on the Blu-ray cover may display A,B,C if it's region free or it may just display the region code for that area (B for example in the UK)
it's a 50/50 chance that if the title is showing Region B only that it's either locked to B or if it's region free
you can use this

titles tended to be locked to a certain region for license issues only. if a single company has worldwide release license then chances are that it will be region free (mostly the bigger hollywood studios like warner, Universal etc) . only Fox used to region lock their earlier titles
a lot of the smaller companys (Arrow, Shout, Scream Factory, Anchor Bay, Second Sight) tend to
Hope this clears things up buddy
