@psycik I feel your pain. I have been working to improve our parsing of the EPG data we get from Gracenote. Sadly so much stuff in NZ is missing the Season/Episode data, or is is hidden in the Synopsis, or worst still, Movies are tagged as “Episode” or “Programme” so they get parsed as a show. or sometimes something on 20/20 or another “special edition” news story that should be a documentary is tagged as a “Episode” instead.
I’m hoping we can improve things over time, but for the most part the issue does stem from the data we get from Gracenote.
An alternative option you could try is to use an XMLTV feed (which you can use as an alternative to the Gracenote EPG during the DVR setup process) such as the one this NZ guy has for his TVHeadend setup http://www.matthuisman.nz/2016/10/freeview-nz-xmltv-epg.html
