Not up with the latest of technology at all so advice needed .. want to ditch Sky and try and get tv some other way .. normally watch Documentaries and enjoy movies .. have a Pioneer Kuro tv and I don't use 5:1 through the hifi (Denon Avca1 and POA t10) .. any suggestions .. can't be bothered trolling around to see what features there are or compatibility with Nvidia set top box or amazon box etc etc
