With the removal of BBC3 from freeview, I'm looking at connecting my 1800-T to the internet (PVR connected to CRT TV by SCART). Does it have to be by ethernet cable (difficult as PC upstairs and telly down) or will a dongle work? If a dongle's required, will any old one do, or does it have to be the specific Humax one (http://tinyurl.com/zyatrj5 or http://tinyurl.com/hfyrpwo)? My internet speed's 3-4Mbps. Is this fast enough, or should I forget the idea and buy a modern telly?
