mark: Could you please clarify on a point. When you say that you run an HDMI to the TV and a red and white directly to the Hi-Fi, where are you getting the red and white from?
Is it one of the older Sky HD boxes that had analogue output sockets?
It would also be of assistance to know the Brand / model of TV that you are referring to.

alan: As you are only 4 miles away from Crystal Palace, I would be inclined to use a standard log periodic type aerial in the loft, provided that is that you dont have to face it into a water tank to obtain the correct angle for the transmitter, and also that it isnt facing through the adjoining walls of other properties, as if it is, then gutter mount it. (Fixings permitting!)

alan: Something like as seen in the link would suffice, as you don't want to over do it then suffer from overloading problems come next April when Crystal Palace switches to high power operation.

Bill: Channel 52 is on very low power at present and so there really isnt much (or even worth) trying to do anything about it, as its only ten days until switchover stage 2 takes place, then your problem should be completely rectified.

Mark: You are only one mile away from the local Leicester transmitter and are you sure that your aerial isnt directed towards that?
When looking at the signal strength also note that Mux channel number associated with it, if on your local Leicester transmitter then BBC1 is on Ch25 / ITV1 Ch28, but if Waltham then BBC1 is on Ch61, ITV1 on Ch54.

Mark: Well, I do realise that the box you are using is very limited in its tuning facilities compared to a normal Freeview one, but if you can receive ITV4 (EPG 24) / or Dave (EPG 11) then its Waltham you are receiving these from, as they are not broadcast from the Leicester transmitter.
That said though, its possible that your box is picking up the main BBC/ITV channels from Leicester, these being lower Mux channel numbers, then the remainder of channels is being filled in from Waltham, which will (in theory!) be much weaker. Of course should you had mentioned the channels that you are having trouble with, then that would have somewhat taken the guess work out of the equation.
On the subject of the aerial, another way to tell if your aerial is set up for Leicester is to look at how its mounted, if its with the elements up and down then that's for Leicester, but if horizontal its Waltham. (This of course entirely dependant on the installer having mounted it correctly!)
Finally, on your initial posting where you mentioned thinking about a new Freeview box, I would without hesitation endorse this as being a good idea!

Mazbar: Yes! you are quite correct on this, and indeed I should have added this qualification to the others mentioned.

Iain: If you are referring to the first post code provided then it depends on where you are receiving the signal from, as if its Fenton ITV1 is on Mux Ch33, The Wrekin is Mux Ch23, or from Sutton Coldfield its Mux Ch44, however this is forecast as being poor for reception until the 21st of the month.
These channel numbers being given to enable a manual tune to be carried out "if" EPG3 is not being shown in the list, if it is then ITV1 might already be found up in the 800 channel ranges.
You can still use your VCR "if" the Freeview TV has output facilities via its scart socket, you would of course not couple the aerial into it.
What model number is the TV?

Philip Crack: Although the trade predictor indicates that you presently be receiving Mux Ch67(ArqB) OK, the channel these programmes are on, your reception situation should improve in two days time (14th) when Ch67 changes to its final allocation of Ch48.

Andrew Lowe: Although lots of other complexities are involved in this, but put very simply, this is because that pre-switchover multiplex transmitters were started up operating on relatively low power levels, the reason being so that they would not interfere with the more distant viewers reception of other transmitters operating on the same frequency covering an adjacent area, this usually on analogue although it could also be very low powered digital.
The switchover process involves all of these pre-switchover transmitters (usually six on a main station) significantly (as far as PSB is concerned) increasing their power levels, which if that was all that was done could then cause problems to the more distant viewers referred to, and so to avoid this happening their operating frequencies had also to be changed, this being why re-tuning is always necessary to enable viewers to keep track of the changed frequencies / channel numbers, the only reason for it having to be done on such a number of occasions (some areas) is because of the number of multiplex transmitters involved, and the automatic chain effect resulting by any change.
Analogue is/was basically a stable well established system, and this is why retuning was never really necessary.
