I primarily use Freeview input to my Tivo (via a Sagem STB) however I have a requirement to use the UHF output from a Humax 9200 PVR as input to my Tivo. (You might well ask - not for recording, but for redistribution of its signal around the house). How do I set up my Tivo to do this ? When I go into "channels I receive" it only lists those channels which are recognised broadcast channels - I want to use Channel 36.
