Thought about getting a flat screen TV Yorky?
I usually get a significantly better international connection when I use a VPN service rather than a direct connection through my ISP. This usually results in less or minimal buffering but this is always dependent on the source. If the source is not good then nothing will stop the buffering problem. I might add that with a VPN I usually get as much as 20 Mbps download, as opposed to less than 5 Mbps with the direct ISP link.I have a Chromecast in the bedroom connected to my HD TV.
[Edit: And my "high speed" internet connection still suffers from "buffering"]
Back in the UK, I refused to pay Sky for either a second box or the wired second room facility. Instead, I bought two AV sender/receiver devices which plugged into the 2 TVs via Scart leads, plus a second Sky remote. The result was perfect images and sound - in both rooms (ultimately extended to 3 rooms by purchasing another AV receiver.) TV's in Thailand don't seem to have Scart sockets (though they all have AV sockets of course.) Has anyone tried to use the Thai AV sender/receivers over here in conjuction with a Truevisions box?
