Having the same problem with sports channels, picture goes blurry continuously. Tried 3 different NowTV boxes and stick in 3 different places, result always the same, picture constantly goes blurry. Please fix this issue, NowTV, sports channels are unwatchable.
It's the same on Windows 10 player whether WiFi or Ethernet. And the same on a stick. Yet, BT Sport is ok as is football streamed on its website by the BBC. Even Premier Sports is better.
It's NOW TV that's at fault. I won't keep paying for such a shabby service - just throwing money away. It can't be my connection when other streaming services are OK.
