Someone above talked about which channels I'd been tuned to. I tried to work out which - it's CH23 for BBC4. But when I went into signal strength, I got a reading of 99-100 for CH23 on Tuner 1That could well be contributing to your problems; it sounds to me as though the signal strength could be too high. The fix is to install an attenuator in the aerial cabling (or if you have an amplifier turn down the gain or remove it).
You make a good point Martin. I just went to one of my new recordings on the 5000T and found it had the very same problems regarding signal pixellation on recordings that I had with my Fox T2 and which failed completely a couple of weeks ago. I hope this doesn't mean that I've trashed one of the tuners on the 5000T
I have a plain roof aerial, no amplification. I've just switched to an old portable indoor aerial and it's now safely down to 67% strength, which will do until I get an attenuator - I have a Maplins in my local area - will I get one there?

Having too high a signal will not damage your tuner it just drives the tuner beyond the point that the output linearly follows the input creating distortion. Technically it clips the peaks of the input signal.
Yes you will find a variable attenuator at Maplins but you will pay through the nose for it.
