I also never watch LiveTV (except the Dallas Cowboys game a few weeks
back).  *But*, I have 2 Shield's in the house running Kodi with the MythTV
PVR Plugin that watch LiveTV all day long practically.  Never an issue in
over a year, so I cannot say LiveTV does not work, just in certain
configurations I would obviously say :)
