No, I had exactly the same results on the living room telly, the living
room PVR, the living room Samsung that normally displays the CCTV matrix
and the office TV set.

I put the Samsung on BBC4 HD whilst I watched a programme on the
adjacent TV set. The Samsung abruptly went from the caption to the
proper programme at 12.25 (ish) so I checked the other tellys and they
were also back on the proper programme.

It was deffo a transmission fault.
