Now that I have my Mac Mini working seamlessly I wanted to have the normal Freeview 7 Day EPG, not just the 24hr one included in the stream. There was a handy scripted shared by Fossie on Geekzone but that was posted a few years ago and no longer works (as the geek.nz xml hosting was no longer live) so I took it on my self to fix it with the new location for the XML (now nzepg.org).
The attached Zip includes the updated script and and a compiled app of the same script. Both will do what you need to automatically download the xml.gz, uncompress and then send it to EyeTV. You can use iCal to automate it to run every week so your EyeTV is always up to date. Sweetbix.
