In the last 4 weeks (approx.) the FREEVIEW signal of ALL the BBC channels has been poor (pixelation,pauses in movement and audio. This is often worse early morning and has occured since various othe channels have been added to this service (Greenhill transmitter South Pembs.)
As BBC is a PUBLIC SERVICE transmition, WHY?

J.L.Townsend: With digital television, multiple services are carried on the same signal (and therefore same frequency). Each signal is known as a multiplex (or mux). Each former analogue service occupied the space of one digital mux.
There are six muxes, three Public Service (PSB) ones and three Commercial (COM) ones. For a list of service by multiplex, see:
DTG :: DTT Services by Multiplex
All BBC standard definition TV and radio services are carried on PSB1.
There have been no additions to the Greenhill transmitter. The COM channels have choosen not to broadcast from the smaller transmitters and are never likely to do so. See here for an explanation:
Londonderry (Northern Ireland) digital TV transmitter | ukfree.tv - 10 years of independent, free digital TV advice
Assuming that the new channels you are referring to are Commercial ones then, based on the Digital UK predictor, the only conceivable transmitter that may give you these is Preseli. On the basis that the COMs are being received from that station, perhaps PSB1 is also tuned to Preseli rather than Greenhill.
Bring up the signal strength screen whilst on BBC One. Receivers usually give the UHF channel (or frequency) that they are tuned to. For Greenhill it will say C24 (498.0MHz) and for Preseli it will be C43 (650.2MHz).
As Greenhill's channels are within the first third of the band and Preseli's are in the mid-third, when you run the automatic tuning scan unplug it when it gets to 30%, or past C30 if it gives UHF channel numbers as it scans.
Because the Commercial broadcasters have not been mandated to provide the same coverage as the Public Service ones there are some viewers who will be without. Some viewers may be able to receive the full service with a different aerial and in some cases this will be from an alternative transmitter. In your case, you "may" be able to receive all channels from Preseli.
I emphasise "may" because there is no given and predictors are just a rough guide; the only way is to have an installer investigate.
Looking on Google Streetview (photos taken August 2009) I can see quite a few aerials on Preseli. With this in mind, if you are using Preseli then perhaps your TV has tuned to Greenhill instead. If so then unplug the aerial for the first 30% of the scan.

Transmitter engineering: How much longer is the Greenhill transmitter work continuing for?

M Schofield: As no one on this website has any connection with any broadcaster or transmitter company we don't have any further details for any engineering work. It's unlikely that the work will continue over the weekend but could continue next week if there is more to be done that couldn't be completed today.
