Isn't it time to remove the Mux 2* to Mux D* entries in the 'How do the old analogue and currrent digital signal levels compare?' table above?

franky: It's "October 2013", rather than "13th October".
You should probably wait to see if you have a problem first, as you move from "good" to "marginal" on the HD mux only.

franky: It's only a prediction and therefore not a forecast of what "will" happen.
There must be a reason that the prediction changes, but the Digital UK predictor doesn't give anything away on that score.
I don't think it's anything to be concerned about.

Can anyone give me an answer to a query regarding Channel 4, I called round to my nan's house on Monday (July 22nd) she has a Panasonic widescreen dtv in the living room, in the kitchen she has an old 14 inch portable with a settop box that came from tesco's.
Both have given no problems and have excellent reception, but I noticed that the Channel 4 picture had black bars at the top and bottom (larger than I had seen before) Panasonic was completely fine and I was there a couple of hours and the portable stayed the same even when the programme changed, Channel 4+1 is the same but I did not check E4 or More4, all other channels on the were completely fine with no black bars.
Is this something that Channel 4 are doing ie maybe trying out a different broadcast type or is this something at the transmitter as I know thaw have been doing engineering work, any advise would be gratefully received, thanks in advance.

Jason: Was you nan watching a film or an old programme? Flat screen TV's are whats called 16:9 - they are rectangles, whereas old CRT TV's are 4:3 - almost square. Widescreen films are even more elongated than widescreen TV's.
If you watch something like Dads Army on an old CRT, its fine - because the programme was made to fit that 'shape'. If you watch a modern programme, the ends tend to be cut off, and if you watch a widescreen film, you end up with a 'letterbox' effect, with black strips at top and bottom. Its called the 'aspect ratio'. I suspect that thats whats changed, and you can vary it in the TV's setup menu.

MikeB no it was not an old programme it was an afternoon so we are talking Countdown and Deal or no Deal, and its also been constant so its all programmes, the black bars actually look like the ones you get if a widescreen film is being shown and watched on a 4:3 tv, it almost looks like the whole station is being broadcast in a full widescreen format.
And yes I do know about the difference between 16:9 and 4:3 ratios, it just seems strange that its happened recently, I also have and old portable myself so I decided to try that at mine with a set-top box and got exactly the same result.

Just another note to the above post, the 4:3 pan and scan option is enabled in the set-top box menu and this works ok with all the other channels, its the same setting that is enabled on my nan's set-top box as I remember setting it up for her.
I'm just wondering if there is a signal that's broadcast with the programme that enables this 4:3 pan and scan option to work, maybe its been disabled for some reason by channel 4.

Any thoughts on this Sudbury problem ?
My TV will not tune the Ch60 output (Pick TV etc), it pauses as expected while tuning but never reports any channels.
However my PVR and PC are still receiving Ch60 just fine, as was the TV until I did a retune a couple of weeks back.
At CM9 6HG, a clear view of the mast, and all other MUX are full strength and no pixellation or errors.
TV is Sony.
