We're trying out some software this week, testing against MC's UPnP/DLNA Server. I thought I'd document a little of it. (For definitions, please see Wikipedia's
DLNA article.)
Cidero has a Media Controller that acts as a UPnP Control Point. It has characteristics of a remote control, since it can choose content on another device and play it on a "renderer" (a TV, for example).
When you run Cidero, it searches the network to find UPnP "devices" and "renderers". MC's UPnP Server is a UPnP "device", and so it is found. The control point can find an MC library and play it on a UPnP or DLNA "renderer". You can think of it as client-server, with control off-loaded to a third object.
To get this working, I was using a build of MC that is not yet released, but it may also work with build 111 from the top of this board.
Settings were stock (no changes). DLNA was unchecked in Advanced. Conversion was set to "Always Convert", MP3, and VBR.
