As I said above, this should be documented somewhere. I can't remember, but I suppose I must have written my own /etc/minidlna.conf as that is what man minidlna says.

Correct. I had forgotten that. I have now re-edited the service file and everything is now working the 'openSUSE' way.

Many thanks for your help.
