Following grahamlthompson's advice I have managed to connect my computer to the Foxsat box and loaded Raydon's File and Media Package. This involved bringing my router to the box, connecting them with ethernet cable (socket in the back of the box) and updating using internet (telephone extension cable into living room to router).
As I understand it, the key to recording non-freesat channels is to move them into the freesat channel list. I have installed the interface and can see a menu option "WebIf channel lists" but the list is only freesat and I can't find the others.
I searched for this topic without finding it.
How do I add non-freesat channels to the freesat list?
