After a new update (DSM 5) for Synology I am able to install twonky and the beosound 5 encore works perfecty with this DLNA server.
So there are some servers that do work (synology built in media server, twonky) and some that don't work (minimserver, plex, serviio)
I'm not sure it that's related to the client or the server.. But let's hope upnp devices will indeed become "universal" in the future.
Cheers, daf
