> If they are indeed shipping GPL code for which they have no copyright

They do include Rich Wareham's libdvdnav, Håkan Hjort's libdvdread and pieces of Sun's java stdlib.
They know what they are doing, see makemkv-oss-1.17.1/mmgpl/dvdnavsrv.cpp

> Still, I don't see any harm in shipping this as a package in non-free, right?

As long as you can provide full source of resulting package, IMO.
