Well, we're making progress.
I was able to access the server from my tablet after re-starting Mezzmo on the PC several times. Now I'm able to view the library and select any video to play. The issue remaining is that the tablet shows only 2 devices: the tablet and the Yamaha AV Receiver (see screen shot).
It does not show any of the other devices that the PC shows. Obviously it has to show my Sharp TV in order to play movies on it. Pressing the refresh button on the tablet screen does refresh it but still nothing except show the same two devices.
