The Services API is the preferred way to talk to
mythtv. Though, there are still some useful commands
in the old part of the python bindings, which interface
directly to the SQL database and the protocol sockets.

Bill warned you already, that python3 on MythTV v30 is
not supported.

The traceback of your python3 example shows:
> MythDBError: Could not find setting 'BackendServerAddr'
> on host ''
and, usually, tracebacks tell the truth:

Please post the output of

  FROM settings
  WHERE (value = 'MasterServerName')
     OR (value = 'MasterServerIP')
     OR (value = 'BackendServerAddr')
     OR (value = 'BackendServerIP')
     OR (value = 'BackendServerIP6')
     OR (value = 'ListenOnAllIps')
     OR (value = 'AllowConnFromAll');

and the output of your 'Host' value in 'config.xml'.

According ticket #13024, the IP of the setting 'MasterServerIP' must match
the IP of 'BackendServerAddr' or one of ['BackendServerIP', 'BackendServerIP6'].
