Since I added Sky HD to my BT package in December 2015 the SKY HD picture breaks up but only when demand is high eg a big football match. Most of the time the picture is fine (BT youview box > Ethernet to Home Hub 5, Infinity 2 etc)
All my HD programmes are 100% fine including BT Sport HD etc.
Example: last Sunday we watched Man Utd V Arsenal, picture was fine. At 4pm when the League Cup final programme started, the picture breaks up (Pixelates) so we had to watch on Sky SD.
I've contacted BT Support several times and they can't provide an answer yet alone a solution and now they are asking me to contact SKY!!
Have any of you BT Youview customers experienced this problem?
