My understanding was that you could record a channel and watch another simultaneously? Well at the moment I'm recording The Apprentice and can only view a very limited selection of other channels rather than the full list. Any ideas as to why? I have a quad lnb with dual cables attached to the freesat pvr box...
Two suggestions
1 you installed the stb using only 1 cable and then added the second. The second cable's prescence is not automatically recognised so you need to do one of the following
Factory reset - watch for 2 cables recognised message
or
Change Connection mode in the secret menu
Enter the setup menu
Press RED GREEN YELLOW BLUE GREEN YELLOW BLUE
Change connection mode to 2 cables (same)
2 The 2nd cable is connected to the wrong connection. (The 2 outer ones are the correct ones). If so put right an do the above
Incidentally depeding on what you are recording, even when recording two there should be a selection of 3rd channels you can watch, under the right circumstances you can watch any channel while recording two
