I have just moved house and I'm having a few issues setting up my Vu+ Uno running Vix 5.2.045

In my old house I had the Uno connected to a motorised dish and everything was working fine, I no longer have a motorised dish so I have opted to just take the satellite feed directly from my Sky dish. I set up tuner A in single mode for 28.2E but when I perform a scan it only picks up around 100 or so channels.

When I try to run AutoBouquetsMaker I get an error "Failed to tune SKY UK on tuner A"

As far as I can tell it looks as though it is unable to pick up most of the transponders, if I flick through the transponders on Signal Finder most show no signal but some seem to get a decent signal (See photo)

What could be causing this? The cable seems to work perfectly when connected to the Sky box so I don't think a faulty cable would cause the issue?

Any help would be appreciated as I'm tearing out what little hair I have left! Thanks in advance.
