Not sure why documentation of LinuxMCE's UPNP client is so evasive, but searching for it doesn't net any meaningful results other than it's supported? If I already have a UPNP server (pick your server), where in LinuxMCE can I add it as a client to view? Even when using 810's inclusion of Mediatomb, it is certainly advertising the same content my existing UPNP server advertises, but LinuxMCE doesn't have an option to play the content.
thx
