[mythtvnz] EPG update problems

[Paulgir]

Hi All

Till now,due to the lack of a permanent LAN connection,I have been  
updating the EPG by manually running tv_grab_nz-py and then  
mythfilldatabase weekly.
I now have a wireless LAN,so I am trying to automate the process.
I have run into problems.I have followed these instructions:   
http://www.gossamer-threads.com/lists/mythtv/mythtvnz/501519?search_string=tv_grab_nz-py;#501519
Am I correct to think that running  tv_grab_nz-py should automatically  
cause mythfilldatabase to run,updating the EPG.In my case it doesn't.
I can only achieve this by manually running mythfilldatabase.
I have tried to use this alternative method From another thread:

"Oh - and once you're done - here's an easy script to import the EPG data:

#! /bin/bash
wget http://nzepg.org/freeview.xml.gz
gunzip freeview.xml.gz
mythfilldatabase --file 1 freeview.xml --update
rm freeview.xml
exit

Paste it into a text file, save it with a ".sh" extension, make it
executable (chmod +x) then run it as a daily cron task at, say, 3am and
you never need be without an up-to-date EPG!"



This also does not work for me.When I run this script in a terminal I get  
the following output:

mythfilldatabase version: fixes/0.25 [v0.25-94-gec51a97] www.mythtv.org


Mythfilldatabase does not run as a result of this script.
Any suggestions that might get either method working will be appreciated.

Cheers
