[mythtvnz] How do I manage when listings update using tv_grab_nz-py?

[Matt Poff]

I've got this installed and thought I had it working in combination  
with my EIT data (using XML only for TV One) but One now never has  
more than a day's listings in it. When does this script actually run  
by default and how do I control this?

I couldn't see anything in /etc/cron or or /etc/cron.d and the short  
installation instructions here (http://lists.ourshack.com/pipermail/mythtvnz/2007-September/003432.html 
) don't mention configuring a cron schedule.

I have my machine set to wakeup and shutdown automatically as required  
so if there's some default download time in the wee hours its not  
likely to run but I usually record the news so could configure the XML  
download to happen then if I can find out where/how I should do this.

Thanks,
Matt
