Briantist:
A very useful thread, thank you for that.
The Lan-Caster can only extract one Mux at a time (even though it can stream up to eleven channels out to the Network) but I will check the other ones out & see if they are better.
The AV man in today said something about the freeview feed being muxed in to the downfeeds from a quad LNB satellite dish that feeds two sky+ boxes. I will explore that in more detail but it sounds like a variable attenuator might possibly resolve it if the input stages are swamped.

We have a freeview rack card at work in Bradford called a Lan-Caster, made by MediaStar.
It appears that of the Muxes we can see, we now see Belmont PSB1, 2 & 4 at a higher SNR (18-19dB) than Muxes PSB1, 2, COm5 & Com6 from Emley Moor (14-16dB)
The Lanstar documentation says an SNR of less than 16dB will cause blocking but the reality is that the outputs are unwatchable. The media guys blame the aerial guys and they may well be right, or perhaps the card has gone U/S.
Curiously, the retune on the 9th gave signals post 20dB but on the 21st Emley Moor muxes had dropped.
