 The "........" are when its waiting for a response, and the last few lines
 should be fairly self explanatory?

 [[BR]]
 > In my humble opinion "-v upnp" should report on every send and receive
 command sent over the network.

 That is possible. I will try to add some -v network UPnP stuff for you.

 [[BR]]
 > Also I believe there should be a GUI entry for UPNP under settings or
 something that lists all detected devices and there status.

 Having a GUI setting is difficult, because most of the UPnP happens before
 there is a database to check settings in, but uncommenting line 1308 of
 mythcontext.cpp will do a dump of the post-autodiscovery device cache.

 Just remember that autodiscovery will not be called if there is a
 ~/.mythtv/config.xml
