I have used NextPVR but it updates TV guides very slowly. And I can't make the NEXTPVR plugin for Kodi work either.
I also tried SichboPVR, the UI looks very cool, but no audio/video, and no guide either, except that a few channels show guide for one hour only. I have tried to change the setting of decoders, but still can't make it work.
so far the most useful software is EASYHDTV, but it is not freeware.
