I'm not the OP, but I have a similar problem, one channel that will not play Live TV regardless of client (I've tried 2-3 different PCs), but does work in NEWA.

I think that's the relevant debug log, from pressing enter to play the channel to pressing x to stop playback. For what it's worth, I'm using a Ceton Infnitv 6 PCIe on Windows 10, and this playback attempt was from a different Windows 10 machine running the Windows Store build of Kodi.[/code]
