[mythtvnz] No EPG - need temp solution

[Robert Fisher]

I do not fully understand how XMLTV works and do not feel confident to 
get it working with the recent grabbers being discussed on this thread.

I wonder if a "how-to" could be created similar to the notes I made when 
I first set up my system to use Had's grabber?

Here are my original notes:-

1) Download tv_grab_nz-py from http://nice.net.nz/tv_grab_nz-py/

2) Copy tv_grab_nz-py to /usr/local/bin.  Make sure that it
is executable. (sudo chmod +x tv_grab_nz-py)

3) Configure it. Note that the configuration file name must match that
name of the video source configured in mythtv-setup for the
mythbackend/mythfilldatabase to use this grabber.
tv_grab_nz-py –configure –config-file ~/.mythtv/<video sources
name>.xmltv
Step 3 had some problems for me but it was overcome by copying and editing
another <video sources name>.xmltv

You also need to symlink otherwise mythfilldatabase will not work
automatically (it uses the user mythtv)
sudo ln -s /home/yourusername/.mythtv/Freeview.xmltv 
/home/mythtv/.mythtv/Freeview.xmltv

4) To see if the xmltv side of things works run
tv_find_grabbers

This should return a list of all the installed grabbers, which should
include tv_grab_nz-py.

5) To see if the myth side of things works run
mythfilldatabase
Pay close attention to the output of this. If it looks like it worked,
the MythWeb status page should also show a successful run.

6) On the master backend run mythsetup and
a) In Video Sources set “New Zealand (py)” as the grabber for your
Video Source.
b) In General, on the Mythfilldatabase page (its the last page) enable
“Automatically run mythfilldatabase”. Configure time, frequency, etc
to suite. Now Myth should use tv_grab_nz-py to update EPG
periodically. The MythWeb status page shows when it was last run and
what the results were.
