I have a Roku (apart from a static ad on the home screen, I haven’t noticed any problem with them and if it was really an issue I could use adblocking DNS servers), and can play media on it from a NAS drive, or I can plug a USB drive into my router and access it that way. It’s all controllable via the remote and provided there’s good WiFi signal, doesn’t require a fast internet connection. Saying all that, I do have fast internet and usually just stream stuff to it via my phone/tablet and the video caster app.
If you are in the UK, you can legally watch hd highlights of both on ITV4, on the ITV player. If not a VPN should work. There are a number of sites that show illegal live streams, you don’t really need anything except a web browser and ad blocker.
I’m going to guess that almost everyone here is in one of the 3 households that spends less.
