The criteria is actually very simple. If the non-free program depends
on GPL program to work, then they are linked, thus the comersial
program is in violation.
It doesn't matter what interface they use and how they are connected.
This also have to say that all MPlayer frontends should be (L)GPL compatable.
It could be easily tested. Stop the internet connection, install and
run that ratDVD. If it can play DVD without libdvdnav, then it is ok.
