You have to be running LE 9 Milhouse builds - which will give you the updated Tvheadend client...
Then install this updated version of Tvheadend...
Dropbox - service.tvheadend42-9.0.113c.zip
Then on the epg grabber page - you will see 2 options you need to check...
- Scrape credits and extra information:
- Use category instead of genre
Enable both of those, rerun your grabber and reload your kodi epg (either reboot or clear data in pvr settings) and you will have the categories from your xmltv file. Please note that you will not have EPG colors as these are tied top the limited genre codes. However, I personally like having the original catgories and not the epg colors - so this works for me.
