a lot of network issues later, I've got things up and running again. Still, manic moose does seem to interfere with the network functionality somehow, never experienced this before. Had to hard-reboot the Synology Nas for it to be released and read again by the network.
Thought to power down the BDP via the Manic Moose button. After a while went to my auditorium where it's situated and this was on it's frontpanel display:
Shuting down.... a manual (button) power down was still necessary, thus making the software power down in system settings futile i guess. At least on the bdp1.
and now for something completely different, getting our hopes up on a BDP4!:
