EDIT: If you only want to use one line in, go into Preferences, then Tuners & Storage, and change the setting Single Tuner Mode from Disabled to Enabled. On the pop-up screen that follows select Enable. Tvheadend it can be used as a PVR backend of Kodi. Tvheadend is a popular open source TV streaming PVR backend (TV tuner and DVR recording server) software application for Linux supporting DVB-S(2), DVB-C(2), DVB-T(2), ATSC, IPTV (UDP/HTTP), and Analog video (V4L) as input sources. If you wish to try using a tuner that we don’t officially support, you can do so as a “community supported” tuner. Default value: false (= don't read and translate the genre strings) The backend can act as a server and stream the TV and radio signal over your local network. In this case, you can skip the genre translation using this option. That being said I have been using UI client a bit more recently and in a testament to sub's design it does load much faster and remote navigation is still more intuitive.
Option added to never use local paths (fixes MBS ‘play to’ feature for xbmc with the XBMB3C addon) Status of tuners is now displayed in a new ‘Tuner’ tab (tuner configuration is no longer shown in Live-TV tab) HDHomeRun network tuner specific: At time of writing the MythTV light package was version 31.0-54-g445cf1fe6b-0. The TV HAT’s built-in Sony CXD2880 tuner supports DVB-T2 and DVB-T standards (Freeview in the UK), so you can watch all … If by official Kodi addon you mean the "pvr.hdhomerun" addon Kodi ships, it actually also sends the data to Kodi the same way.
Wait for PVR Manager to start and channels to download (This may take a few minutes). If you do not have any channels here, there is no point in proceeding any further.
But the tuner doesn’t know anything about multi-tasking, it can’t handle more than one TV channel at a time. If you get discovery working again, but can't stream anything still, try this addon's Advanced / Stream Live TV channels directly from tuner device(s) setting.
