I'm stumped. I'd try running the tests in two steps,
like this (to simulate the mythtv environment better):

     sudo --set-home --login --user=mythtv
     /usr/local/share/mythtv/metadata/Television/ttvdb.py -v

Thinking that user mythtv has a copy of some module
in it's directory (done with pip install run without
sudo for example.)

OK, three steps: echo $PYTHONPATH while you're user mythtv.
