Fran Shuttlewood : Try carrying out a "manufacturers reset" on the TV prior to following the advice given by KMJ,Derby as far as the "manually" tuning in of Oxfords Mux channels are concerned, as by you being located extremely close to the Woodford Halse transmitter, which is a relay of Sutton Coldfield, it would be nearly impossible for the TV "not" to pick up PSB transmissions from this station before Oxford by Woodford Halse transmitting on channels 25 - 22 and 28 (HD), whereas Oxford mainly uses channels in the 50 - 60 range with the exception of COM7, and Freeview devices always scan from 21 upwards.
By the way, "Manufactures reset" is also referred to by some manufacturers as "Default setting" or "First time installation".
As a recap on that said by KMJ, Oxfords Mux channels are : 53 - 60 - 57(HD) - 50 - 59 - 55 COM7(HD) 31.

Raoul Addie: Try carrying out a "first time install" on the box and see if this makes any difference to the situation, first time install being at the bottom of the list under the "settings" heading.
Unable to check the signal levels expected in your area as no location was given, this being in the form of a post code or one from a nearby shop / post office.

Fran Shuttlewood : That said, and information given, was based on you having mentioned that you had lost your connection with the Oxford transmitter, the news services from same being : BBC One South (Oxford), and ITV (Meridian / Central (Thames Valley micro region), can you verify if this is correct or not?

Raoul Addie: Many thanks for the update!, and pleased that the procedure, as mentioned, has rectified the problem, as its about the only way of eradicating anything lurking around in the tuners memory, and which is mostly responsible for these odd type of problems occurring, standard auto-tuning not always being effective in this respect.

joan josephs: Provided that rain water has not managed to gain access into the termination box on your aerial or coax connected into same, then heavy rain does not really have that much of an effect on Freeview reception, the one exception to this being unless your aerial is facing into tree foliage?
Have you checked with any of your neighbours to ascertain if they are also suffering from zero reception?

Fran Shuttlewood: Your problem could simply be down to the level of the signal being received from the Oxford transmitters being too low, the reason for my suspicion on this is due the fact of you being able to see an indication of a signal and yet you are unable to store it, this in most cases being a symptom of a low signal level that's close to the receivers cut off threshold for reception, or that its being caused by a fault in the TV's tuner, which at this stage I very much doubt if it is.
If your TV strength / quality bar is calibrated in percentages, what does it indicate on BBC Oxford? It would also be of assistance if you could provide the model number of the device in question.

wendy : Or to put it in a nutshell, you would have saved yourself a load of hassle if you had purchased a standard Freesat twin tuner recorder (PVR), these devices being a 100% compatible for use with a dish that was previously used for the reception of sky.
The only point being, if your Sky box was "not" a Sky+ / Sky+HD type? then you will only have one single coax coming from the dish, and although a Freesat recorder can operate with only one lead, it does so in a very limited fashion "as far as recording" is concerned, and so for full operation a second lead would have to be run from the dishes LNB, that is provided the latter is fitted with either a twin or quad LNB.

Fran Shuttlewood : In that case, then your TV "not" being able to store a channel even although its being received at a good strength does give suspicions as to a possible fault in your TV's tuner, as about the only two things that can cause non- storage of a channel are: (1) the signal level of the channels attempted to be stored is too low, or : (2) that tuners memory is full to capacity (overloaded) whereby any attempt to store further channels is rejected, the way of overcoming this particular problem being to carry out a manufacturers reset, but of course, as you have already carried this out then this aspect does not obviously apply.
By the way, do you have a booster connected into your aerial system? my reason for asking being that the signal reading given is somewhat higher than would have been expected at 27 miles away from the Oxford transmitter, and if you do have a booster in line then the possibility exists that input circuitry on this device is being affected by the signal from the Woodford Halse transmitter located at a proverbial stones throw away from you, i.e: on the right hand side of the entrance to the Manor Business Park, checks made revealing that this transmitter is beaming the signal directly towards you.

Fran Shuttlewood : In addition to that said. Taking into account the fact that you have already tried a number of tests and yet the situation remains the same, then about the only options available to you (cost free!) are either to test your aerial out using another TV, or try tuning your TV whilst its temporarily connected into another aerial system, possibly an obliging neighbours?

Mike: Thanks for the info, although "if" the device in question is definitely a diplexer and "not" a combiner, then this device will have the effect of attenuating the signal from one of the aerials as diplexers are designed to combine aerials of different groupings, and of course reception from both the Poole and Mendip transmitters require the "same" group of aerial with the exception of Mendip's COM7.
