I put Mezzmo on a brand new PC a few weeks ago, and it worked perfectly. I'm not sure what's happened since, but now one of my Sony Blu Ray Players says "waiting for server to start" whenever I browse to the new Mezzmo server, and if I use the Android app to push to it, nothing happens. The android device appears to be playing to the Blu Ray player but the blu ray player doesn't do anything. What's extra strange is that the other blu ray player in the house reacts as expected, and the four android tablets with the Mezzmo app also react as expected. What is the usual suspect in this scenario?
