In case others want to use it, I'll list the steps I did to get it working as you quoted a folder that didn't exist, sorry Willy.
To get a full 7-day NZ epg working with your DVB-T tuner :
- Mount a USB stick in Fat32 format, to store your picons and epg data (this is encouraged by all STB forums for better performance).
- Install the XMLTV-Importer plugin if not already.
- Copy the attached files above as they are (ie. do not unzip .gz file) to "/etc/xmltvimport" (there is no "/etc/epgimport" folder).
- Go to Menu>Setup>System>EPG>Settings and ensure all EIT options are set to "no".
- Within the same window, select "EPG location" and click the left< or right> buttons to select "/media/usb/" then click "Ok".
- Open XMLTV-Importer plugin to configure, enabling "Daily automatic import" and set an appropriate "Automatic start time" when the STB is not in use. I also enabled it to "Start import after booting up".
- Press the blue button (Sources) and select "NZ DVB-T XMLTV" then click "Ok".
- Press the yellow button to do a "Manual" epg import, click "yes" in the following pop up window. Note that you should see the number of events immediately growing,
- Click "Ok" and "Exit" out of all windows to your tv screen.
- Click "EPG" to check that the data has populated successfully. If not, just reboot.
- Enjoy a full 7-day NZ epg!
