The picture on the BT sports HD channels seems to pixelate every 30 seconds or so and sometimes when it happens I get the onscreen error message IPC6023. I'm on BT infinity 2 and I get the full 75mb download speed. The youview box is connected directly via ethernet to a HH3. It's almost as if, at times, there is not enough bandwidth for the stream.
I've just done a speedtest and bandwith to confirm my download speed.
