Possibly a stupid question this but can you program the remote to control your TV like you can with SKY e.g. volume does actual TV volume, can switch TV off etc?

That one is easy - No.

DAMN!

This is a guess but my understanding is that pressing another of the top buttons is the number 1 in support calls. Foxed by the numpties.

Multi code not multifunction. If it's any help the original remotes will control the new box (not sure about the new keys though)

I tested the Foxsat remote with in - did not find any problem, You do need to know the new paths i,e, in place of schedule use Media (recordings) > then select planned.
