Sadly, LiveTV does not work on XBMC due to there being no PVR plugin capability for our boxes. Even though the Black Hole Team did release a beta PVR for their image I did not have much success with it.
Even with the Kodi releases now surfacing (OpenPLi Beta V2, OpenSPA 5.005) I see PVR is still not an available option unless I have missed it somewhere.
