I am pretty sure that this is where the data is coming from anyway, so
there must be a misconfiguration somewhere.

I am also aware (AND HEADS UP TO EVERYONE!!!!) that data provider for
tv_grab_nz-py will be offline for a while this weekend, maybe a bit
longer, so let's not clog the place with "WTF" posts. Be patient.
