Chris: "When I try to pause live TV I am getting a message 'No signal for operation' which suggests to me that there is some kind of embedded code or information that is missing/changed from the broadcast of these channels since being moved on Thursday."
I do find this apparent refusal to write to disk interesting. It's extremely annoying that we never get to know the cause after they fix it.
What it points to, it seems to me, is DRM, as this dictates how recording is carried out.
DRM messages normally exist in the SDT and EIT for HD services on the DVB-T2 multiplexes in the form of the FTA content management descriptor. See ETSI EN 300 468.
The FTA content management descriptor is a single byte, one bit of which, called do_not_scramble, controls encryption to disk:
do_not_scramble: This is a 1-bit field that indicates whether or not to apply scrambling of the content item for the purposes of content protection.
If do_not_scramble is set to '1' then scrambling shall not be applied for the purposes of content protection.
If do_not_scramble is set to '0' then scrambling shall be applied where applicable for content protection.
If someone uploads a sample of the Bluebell Hill BBC B transport stream - ten seconds is enough - I could compare it with Winter Hill's BBC B and maybe see a difference.
Here is a ten second sample of BBC B off Winter Hill:

Bill Dixson: The short answer is com8.
It depends on which transmitter your aerial points at, the kind of aerial you have, and whether your receiver is compatible, none of which are known.
If you enter your postcode and make and model of your receiver then you might get a better answer.
