NottsUK: It's my belief that the BBC's use of 1440x1080 is using the Kell factor, to try to avoid annoying artifacts caused by the sampling rate matching the black/white transitions of high-density patterns. 1440 is a Kell factor of 0.75, matching the Kell factor used for analogue SD transmissions and close to that for digital ones.
See Kell factor - Wikipedia, the free encyclopedia and More than just a pretty face... for descriptions of the Kell factor, and the factors used for UK broadcasting (we are/were CCIR/ITU-R System I). The digital factor is a little wrong because the BBC are required to use 720x576 for the main channels, a factor of 0.703, while for 4:3 broadcasters are allowed to save some capacity by using 544x576. A 1.0 ratio would be 768 pixels per line (multiply 576 by 4/3) so 544 is a Kell factor of 0.708.
That said, broadcasts on a system using solid-state CCD cameras and generally viewed on LCD or plasma sets should probably have a higher Kell factor, though the broadcast 1080i is of course interlaced and therefore would suggest a lower factor. Perhaps the fact that the BBC generally still use CRT monitors, for their colour reproduction capability, has affected their thinking here. The Kell factor is stated as being subjective, so it is a matter of taste.
Of course 960x1080 is a factor of 0.5, on the low end even for interlaced pictures, but 720x1080 (factor 0.375) would not have been acceptable.

You do know your channel list is out of date?

Lincoln
I live in Lincoln LN5 9UE and because of our position most of our estate have aerials facing Waltham including myself. Have wideband aerial and a new LCD tv. Over the past year on digital I pick up all the stations from Waltham but I am also able to pick up a number of BBC channels from Belmont even though my aerial is facing Waltham. When the transmitters increase there output after August will I be able to pick up other stations from Belmont. Gordon

G.Hodson: Yes, it's quite likely you will be able to. Depending on the software on your box, when you retune, it might ask you which set of channels to store, it might store the strongest (presumably Waltham if your aerial points that way, although Belmont is more powerful and closer), or it might store the first version that it encounters. The second set might be stored somewhere else in the EPG.
If it stores the first version, you would probably get BBC A, D3&4 and Arqiva A from Belmont, and SDN and Arqiva B from Waltham, as the Belmont frequencies are generally lower than the Waltham ones.
See Digital Region Overlap for thoughts on how to get the services you want.
Note that Belmont Arqiva A and B don't reach full power until November, as they clash with services from Tacolneston. However, SDN, Arqiva A and Arqiva B have the same content at every English transmitter.

Using a freedsat dish and box, can I re-tune a freeview tv set?

The tele has gone bust now and will buy a nerw one at the weekend.

Or will this cause any problem.

Briantist: I see REAL DIGITAL will test the signal within four weeks with a possible launch in early September.
