I need a type of DLNA renderer software on my computer that allows access by UPnP AV-Controllers on the local network.
It shall function like most TVs do, so I can let it run unattended and start videos on it.
Answer
Totem should support this with the right plugins installed. See this blog post http://blog.andresgomez.org/2012/09/05/nslu2-grilo-and-upnp-in-ubuntus-gnome/
It may still be true that the totem is not build with the grilo plugin in trusty.
I was able to get grilo plugin in rhythmbox by starting rhythmbox and enabling it. Go to Tools->Plugins and check the box next to Grilo media browser.
Alternately:
You can install Rygel from Ubuntu Software Center. It supports both UPnP AV MediaServer as well as becoming a MediaRenderer.
