Eileen: Pleased to have been of some assistance! albeit that what I had mentioned was somewhat abbreviated in content to save an over lengthy posting, as there are few other effects that can be experienced connected with this type of situation.
By the way thanks for your latest update and which is very informative, insomuch that even although Ch50 (ITV3 etc) is transmitting on half the power of the PSB channels (BBC / ITV1) you are still receiving it with a 100% quality, its lower reception strength being as would be expected considering the difference in transmission power involved. (PSB's - 100Kw / Commercials - 50 Kw).

irene: OK, I will look out for an update on the points mentioned, and especially the result of the test when the relatively trouble free TV used upstairs is tried out on the downstairs aerial system, as although you say that your TV is a Bush this is just a name tag, and the reason why I requested the model number of the device as this pins it down to a particular model of chassis, some good, but with some others unfortunately not so! Bush in common with many others not actually manufacturing anything.
If it wasn't for you having reported that the upstairs TV is OK using a different aerial then I would have considered that your problem might be one common to the area, but "if" what you have said regarding the reception on the upstairs TV being OK is the case, then its either that your main TV possibly lacks sensitivity or that the aerial it uses is deficient in some way, and with this being irrespective of what the aerial man might have said.
By the way EPG channel17 is on the same transmitter as Sky news, this being why both are affected.

Steve: What you have said suggests that your second hand box is defective as the power units fitted in these older boxes are prone to failure.
Although it may be a bit of an inconvenience, but try your HD box in the multiroom boxes position using only the HD boxes LNB1 input, as that will soon reveal if either (1) that the outlet port used on the LNB for the multiroom contract box is OK or not, or (2) that should it be OK then your latest acquisition is defective.
You could of course just try the DRX400 in the Sky HD boxes position but using only one of the dish feeds, this can be anyone of the two feeds as they are technically identical.
By the way Sky were not exactly correct in what they have said, as OA downloads does not help your type of problem.

Roger: Just to add to that already said by Les Nicol & Stephen P
The aerial socket on your Grundig Sky box is an input used in conjunction with the boxes RF1/2 sockets, because if a coax is run from either of these sockets to a remotely positioned second TV (set on analogue if a dual standard set) it will enable the Sky programme on the main TV to be viewed on the second TV.
The plus point being, that if the normal aerial is then connected into the socket referred to then the Freeview signal passes through the box and onto the second TV along with the Sky programme, this enabling the second TV to view either Sky or Freeview, the latter of course only being applicable if the TV being used is not an old analogue only set.

Trevor Robinson: If you are thinking along the lines of using a gutter or roof mounted FM dipole then you might just get some form of reception albeit it most likely to suffer from fading, as Great Yarmouth is as the crow flies slightly over twice the distance from Crystal Palace as Clacton on Sea.
The other problem you are liable to experience is that of BBC Radio Lincolnshire competing with BBC London as both use the same frequency, and because of an FM receivers capture effect you could well find that one minute you might be listening to BBC London and on the very next moment BBC Lincolnshire, as both stations are being received well outside of their coverage areas and the effect mentioned is commonplace in these type of situations.
Putting it simply, should you be a bit of an enthusiast then its worth a try, but if you are not then I feel that there is only a very slim chance of success.

Nick: If you cannot get Pick TV (11) either then you haven't received ArqA/Com5 as these three programmes are all on that transmitter, Yesterday not!
I would blank the channels already stored out by carrying out a re-scan without the aerial being connected, then once complete reconnect the aerial and carry out another auto-tune and checking the results.
Its always best carrying out a factory reset (or default setting) rather than the aerial out procedure, so if you do not have success on the second rescan then try the factory reset.

Hannah: Not if you use the "other channels" procedure, as the original EPG listings does not get altered in any way.

steve: If the two aerials on your roof are facing the same direction then your problem is suggestive of the aerial that feeds downstairs TV having a bad connection somewhere along the line, and this could be from the TV's coax plug to where the coax is terminated on the aerial.
You should carefully unscrew the TV's coax plug to make sure that a strand of wire from the braiding hasn't accidentally wrapped itself around the middle core of the coax, this being quite a common problem, if though it appears as being OK then the problem has to be at the aerial end if its a continuous length of coax.
The only other possibility "not" connected to the aerial is that when you retuned your TV it picked up the incorrect mux channel, the easy way to tell being to try one of the TV's from upstairs on the downstairs aerial and carry out a check on the problem channels, if it works OK then the main TV requires another re-tune.
By the way if you are receiving from Sutton Coldfield then Pick TV etc is on mux Ch45 (match being BBC1 on Ch43) if though you are using The Wrekin then Pick TV is on mux Ch 44 (BBC1 Ch26)
The mux channel should be indicated on the signal check screen along with the strength / quality.

Ian: When you say "losing the picture" are you meaning only the Freeview picture?
The other point being, that by you not having revealed your location (post code or one from nearby eg: a shop) then its impossible to check details of the transmitter covering your area as you could be located anywhere in the UK.
Another aspect that it would be beneficial to know is if your aerial system is exclusively yours or is it communal?

irene: Thanks for the update / explanation.
Your last statement interests me insomuch that "if" your reception is OK on the newer upstairs installation and you can receive the channels on it that you are having trouble with on your main system downstairs, please confirm if this is the case, then there is no reason why this should be happening, as it could suggest that there is a problem with this installation.
The other point I wondered about is do you use a booster on your main aerial? and do you know if your main TV has a manual tuning facility? if you are not sure then please supply the model number of the TV.
Regarding your aerials, if you are able to see them are both of them facing the same direction? if not, is one of them mounted vertically with the elements facing up / down?
Just to give an idea of directions, Pontop Pike is at 295 degrees, Bilsdale 164 degrees and Fenham @ 295 degrees, there is also you local Sunderland transmitter located just over 1 mile away @167 degrees and which is just about in the same direction as Bilsdale, the difference being that Bilsdale's aerial would be horizontally mounted whereas Sunderlands is vertical. I will say that most I am able to see in your area appear to be facing towards Bilsdale, which on the reception predictor does not suggest as being the best for reception, as Pontop Pike is. (in theory!)
Maybe you could update on these points, but the other thing I would like you to try is to carry out a test by taking the upstairs TV down to the living room and see how it performs when connected into the living room's aerial system, and in particular how the BBC channels perform when viewed over at least 15 minutes or so.
