jrsilvey Is there a program that will make KDE broadcast multimedia over DLNA that works?
kodi? It is widely available and well-supported.
There are actually lots of dlna servers that work on Linux and it shouldn't really matter which DE you are using.
If kodi doesn't work for you, I can take a look at rygel and try to figure out why it isn't working for you. I have never used it but I would be willing to give it a look.
