Buenchico,
So sorry for the delay - I do appreciate your help.
Well, I tried all that and there didn't seem to be a problem. Talk Talk finally decided to send an engineer out, and I only had to wait one day, which was great.
He took one look at my set-up and straight away knew the reason it was being so slow and taking ages to load a film. The view box plug/signal box was plugged into an extension lead, behind the TV, which held the TV plug, the DVD plug and my sons Playstation plug. This then ran to the wall - which was the route of the problem.
He said the You View plug/signal box must go DIRECTLY into the plug socket on the wall, and that the extension lead was acting as some kind of barrier and breaking down the signal.
He then looked at my plug socket and said because it was low down, the You View plug would not fit into it, but he could supply me with some "newer models" that would fit just above the floor and solve the problem. He said I would need two - at a cost of £50 each!
I explained to him that the box was only fitted a few months ago, and by a Talk Talk engineer, so surely he should have realised this would have been a problem. He said "no, because this fault has only recently come to light, which is why we now offer these new plugs/signal boxes".
Anyway, he fit them, for free, and the problem is now solved.
I watched Pinocchio without any disruptions at 5am this morning :)
