[clug] MythTV backend uncommunicative

Are the front- and back-end on the same machine? If not, then ensure that
the exact same version is installed everywhere. Mythtv is amazingly unforgiving
any version mismatch (if I was doing such a design I would be fires on the spot).
Even if I did not mention that the client talks directly to the DB...

Can you browse to port 6544 on the server?

This, of course, does not matter if the frontend is a DLNA client.
