I'ts a matter of the UDF-Version.
I'm no expert, just missing the ability to quickly look into common
flowting DVD discs, which doesn't work so I asked ddg.
It seems today's DVD's are all UDF2 – FreeBSD has only support for UDF

Blu-ray's seem to be in UDF2.5:
There's also the UDF2.0 FreeBSD-10-driver mentioned:

Hope this helps, unfortunately you'll have to enable UDF2 support on
your own.
