[mythtvnz] tv_grab_nz-py set up

[Paulgir]

I have installed this script as per this thread:
http://www.gossamer-threads.com/lists/mythtv/mythtvnz/491620?search_string=tv_grab_nz-py;#491620

In myth backend set up >video sources>configure
the messages indicate it is downloading the data successfully.
The data does not appear in the schedule.
I have also tried  tv_grab_nz-py --configure in a terminal.
Also, I don't have a /home/myth/.xmltv/tv_grab_nz-py.conf file..

In normal operation,does tv_grab_nz-py run automatically?If not how
is it normally run? Via myth backend set up?
