Thanks for the suggestions! Tried all options re my tv. However - as every flat in my block without a sky dish, local house, the local pub and the hotel down the road has also lost every BBC channel - i'd suggest the problem lies somewhere outside of my 2 month old Toshiba!
But having contacted digital Uk several times via email and spending a couple of hours on the phone to them the response has been exactly the same - there's no fault with the signal!

Oh and to Michael Perry - i'm in Swindon. But was in a Bridgwater hotel most of last week - and guess what! They've lost all BBC channels too!

Rob: Communal aerial systems may need adjustment to work with the new channel. This could, perhaps, explain why a hotel may have lost access to BBC services.

Now over a week without the BBC. Watched Doctor Who on the computer last Saturday, other than that what exactly is the license fee for????

Since digital signal switch over, get more picture disturbance, when we pay television licence fees we should receive signals that avoid this

To jb38: I never said it was the 'bee's knees' and at that price it was bound to be limited (decent ones are around £4000!). You need sufficient signal strength first and then decent quality (freedom from reflected signals, co-channel noise, etc) to allow in-built error correction to get a usable signal (strength and quality) for each Mux. Even an £8 device can show if your signal is too weak and can help correct alignment. It's not the final answer though,just a starting point.
To Chloe and Rob, et al: There cannot be a fault at the transmitter as more than 1,000,000 viewers are receiving all BBC programmes, but some (it seems they are largely to the south and south west of the transmitter site, but not always) are having problems resolving the new Muxs. Hotels, flats, some urban low-lying areas, etc may have communal aerial systems and these filter what channels are distributed and may well need adjusting (the large firm I worked for before retiring had many contracts with hotels and they all had that type of distribution equipment). Some Freeview equipment is not as well designed as we might hope and some cope poorly with the adjustments made to get 4G space. Some group C/D aerials may not be as good in the Ch 48 and 49 region as they ought to be. Some receivers need to be completely reset and all memory of what channels they used to have removed before doing a full retune as if starting from initial installation again.
So Rob: If your fellow flat dwellers are having the same problem get your housing agents to have the aerial distribution system corrected (the filters probably need resetting) and then do the full retune. (BTW, I live near Lyneham)
On a general point, can anyone shed light on why so many of the people reporting here are in the areas to the south or south west of the Mendip service area? Huntshaw Cross, in North Devon just south of Barnstaple, shares three channels, 48 52 and 56, but not 49 so I doubt that is a cause. Any ideas?

@Geoff, your licence fee doesn't entitle you to good reception any more than a marriage licence entitles you to a good wife. I expect over the years the wording has changed, but at one time it was simply for ownership of the receiving apparatus (whether it works or not).

I have written to BBC Radio and Television Reception, www.bbc.co.uk/reception, in the hope that they might come up with some help for people still having problems - I'm not holding my breath though.

Michael Perry: Well on having twice read over my reply I cant honestly say that I noticed anything said by me that could even remotely be interpreted as inferring that you had made that claim for the device, nor if it comes to it criticising anything said by you, but just simply pointing out to anyone "other than yourself" who may also have been viewing the posting and likewise thinking about purchasing the device to beware of its limitations as well as the reason for, as its an important aspect and which I am quite sure is not brought into the equation by many, and who although in past years may have been perfectly proficient at setting up aerials used for analogue reception but though not being fully aware of the pitfalls that's liable to be experienced with digital reception, and especially so when its being received under difficult conditions, this being the main point of my reply.

Michael Perry: The odd thing about the reception problems which are mainly in the Taunton direction is the number of cases that report poor reception currently on C48 which did not give problems prior to C49 being adopted for BBCA. Makes one wonder if just maybe there is a problem with the radiation towards the southwest. Among the countless thousands of viewers who have no problems there could still be a significant difference between the strengths of the signals being received. I agree with the other points you make, additionally viewers who have interference on C49 might have always had it but of course not noticed it. Equipment that has the RF modulator set to C49/50 and radiation from poor quality HDMI cables could be factors for some viewers.
