Matt,
Given that you can receive BBCA, BBCB, and D3+4 satisfactorily from Hannington and that your reception of ArqA, ArqB and SDN suffers from break-up (sometimes non-existent), this suggests to me that you require a bit more signal gain, probably about 3 - 6 dB.
There are two (simple?) ways to achieve this. Either or both may be applicable:
1. A higher gain aerial. A Group B aerial will typically give 4dB more gain (across the required frequencies) than a Wideband aerial with a similar number of elements. A Group B aerial with more elements will obviously give you even more gain and improve directivity. (i.e better rejection of interfering signals from Hatfield although given your location, the direction of your aerial and the location of Hatfield, Im dubious that this is a problem.)
The disadvantage is that a Group B aerial will not be suitable for the proposed Com 7, Com 8, Com 9 (all Group A) and Local Service (Group C/D). However, I would be doubtful that a Wideband aerial would be suitable for Group A reception from Hannington at your location.
2. Improve the downlead cabling. The losses in a typical domestic pre-DSO installation with (what was then) standard coax, wallplates and possibly in-line co-ax connectors can often be reduced by 2 - 5 dB by using better quality cabling and a minimal shortest distance direct run.
The amount of improvement depends on the type and condition of the existing cable and the number of intermediate connections. These are particularly likely where the cable route has been changed since its original installation for decorative reasons, or re-siting the TV.
You can buy better than standard quality cable from many suppliers often under the name digital satellite cable, but I only know of one source for a Group B aerial - www.aerialsandtv.com this site also contains a lot of useful information about aerial selection, cabling, installation and performance.

Thanks again JB,
Yes the 40% is on the Samsung strength indicator - it also shows a bit error level of 4 which I understand isn't great.
Upstairs TV is a Samsung UE22D5003, which doesn't appear to have a signal indicator(that I can find).
Your point about Humax tuners is interesting as I have previously had a F2-Fox T which struggled as well.

Jon,
According to the Samsung manual for the UE22D5003, signal strength display should be available under the Support menu:
Support -> Self diagnosis -> Signal information
I don't know that this actually true!

Richard,
Thanks you're right. Upstairs I have a signal of 100 and a bit error level of 0.
Does that help in pinpointing a problem?

The implication is that your aerial and cabling to the upstairs TV is fine.
Try JB's initial suggestion, 21 May 2012 9:44PM: swap the TVs round. It's a bit of hassle, but it is the simplest method of determining if the problem is with the cabling to the downstairs TV OR whether it's the LE32R41BD itself.

Jon: Well, although as was previously mentioned the R41DB is a set that's not exactly noted for its tuners sparkling performance and indeed is quite the reverse. However, if the Humax box that you reported as having struggled to receive a signal had also been connected to that same point then it would be inclined to suggest that a possible problem exists with the downstairs link, as Humax tuners are known as being able to produce a reasonably glitch free picture on a less than perfect signal that would be liable to result in constant pixelated pictures being seen on some other devices.
Pleased that RichardS gave you a pointer with regards on to how to find the signal strength indicator on your D5003, as I don't actually have the manual for that particular model.
I will look out for your update should you decide to try the R41DB upstairs.

Thnaks for all of the help so far. I've done the swap test with the following results;
Downstairs TV downstairs - Signal 34, bit error rate 4. Upstairs - signal 32, BER 4.
Upstairs TV upstairs - Signal 100, BER 0. Downstairs - signal 100, BER 0.
So it's definately TV specific. But to add a further complication I had perfect picture last night and this morning (8pm - 8am) with a signal of 42 and BER of 3, but by lunchtime it's gone again. Is there any reason for it being time of day specific?
Jon.

Jon: Atmospheric conditions generally cause most signals to vary over a 24 period and its just that most people do not notice this variation when their signal is received at higher levels and well away from the cut off point of their receivers tuner, this commonly known as the "digital cliff" threshold, as should the signal not be running high enough above this level then any slight drop will allow it to encroach on the cut off point resulting in constant picture pixelation or freezing, and with any further drop cutting the picture off altogether.
I think your test somewhat proved the point about the lack of sensitivity that Samsung tuners can suffer from, I will say though that if you used a booster of say 10db+ purely on the feed to the offending Samsung then that would keep the signal level running well away from the R41DB's cut off point, this most likely resulting in it being more reliable.

jb38,
Re your suggestion to Jon wrt 10db+ booster.
Jon's post of 22 May 2012 4:26PM suggests that he has effectively tried this by adjusting the gain on his masthead amp. (Which may overload his UE22D5003, but apparently made no difference to his LE32R41BD.)
I'd guess that Jon's LE32R41BD needs a better signal, rather than just amplifying the signal he already receives - i.e his own suggestion (from the same post)
"... so I might try a grouped aerial, with a 2 way masthead ..."
is more likely to produce reliable reception?

JB & Richard,
Thanks for all of the help and advice you have given.
Richard you are right, adding a booster just for the LE32 made no difference. I've come to the conclusion that I've got a rubbish signal at the aerial which no amount of boosting will help. At the moment a new TV isn't an option, so I've taken the plunge and bought a XB16B and 4 way masthead.
I just need to get my hands on a 9 metre ladder and I'm set! I'll report back when done, but thank you again.
