We have exactly the same, and it seems a few others are also experiencing this issue... Pixelation on Portrait Artist of the Year on Sky Arts from recording @ 01:59. Only on recording and only Portrait Artist of the Year. All other recordings are OK. Have had to watch it on catch-up instead.
Firstly I did not raise this as a stand alone discussion, it was part of another discussion regarding the same issue. It was a comment on another post and was intended to aid any investigation. 1 occurrence could be the V6 box, 2 independent occurrences becomes a bit less likely, above this (as in this case) might show a route cause of the issue.
As stated our experience is that is is only occurring on this recording. Live works (at the moment) as does all other recordings and pausing. We have not tried it @01:59 for obvious reasons. That's why we are recording it! The pixilation starts about 30 minutes in, so would make it about 02:30 at recording time. This has only started within the last 2-3 weeks.
Can you watch Sky Arts live, OK? How about if you pause it and view it slightly delayed?
