Does not work on my TV but did last year.
Keeps dying when watching F1 and tells me to check my connection.
Everything else works so i think they should read their own bloody messages
Wifi or Ethernet cable connection?
Do you have Now broadband?
When you are asked to check your connection, do you find the internet light has gone out on your router?
if not, can you move the PC and the router closer together, even just temporarily, and see if this improves things, and/or use a cable connection if it seems to be a WiFi issue?
What device are you using as you mentioned TV not supported and then tagged in PC.
