I would highly recommend freeview with tvirl too, it is super lightweight and responsive on native "Live Channel" androidtv app. For tvirl free version, if the source/epg is down you need to manually reload the playlist then it should be up again, the premium version does have the auto-reload feature.

Epg is a donation only feature but trust me it is worth it, cuz the developer is very active maintaining the epg to be up-to-date.
