UPNP was using fully qualified domain names to devices that couldn'tt resolve them

I changed my server name in the mythtv-setup from an IP address to a host name while playing with multiple back-ends. This broke the ability to play via UPNP on some (WD TV Live Plus) players. The backend is using the FQDN instead of the IP address in the UPNP which the player cannot resolve.

The solution is to turn all host names into IP addresses. I have included a patch as a proof of concept which allows my WD device to begin to play again.

The patch is still deficient in the following areas: 1) It is possible the DNS resolver will not return any addresses. This isn't always handed. 2) The backend music UPNP handler doesn't cache the back end's IP address like the Video and TV handling. This will hammer the network with resolver requests for every song and will ultimately cause a crash due to the above case of not checking the return.

Patch to allow the backend to use IP addresses instead of hostsnames for UPNP

The other way to fix this is to use IP addresses, not names.

I will look into this after 0.24

Setting your backend to a hostname instead of an IP address is not supported. That's why mythtv-setup asks for an IP address, not a hostname.
