OK, Couldn't get Sky installed because of my rural location (trees in the way etc etc). Anyway, My only other option was to download the NTV app onto my TV (Samsung)and buy a sports pass to watch the footy.
Before buying the sports pass I checked that my internet connection was fast enough. I know it's only 15MBps out here in the sticks, but it's more than fast enough for streaming TV according to NOW.
Long story short - it's crap. The stream only lasts for a minute or so before breaking up and then conking out completely. Totally unwatchable.
