In Webif Settings>>General Settings there is an option to choose from up to 5 Favourites as your default EPG (or None).
Hmm, I was just congratulating myself that I had bought a Humax. But, above did not work for me
Webif>Settings>General Settings>Channel Group for EPG. choose Favourites1>Set
Receive the confirmation message, reboot just in case it is necessary.
Select EPG and find default is still TV and there is an unordered list of channels.
Select Group>Favourites1 and see the correct ordered list. Close the EPG and open again - back to TV
Now that is a little strange because I have deleted every channel I don't use and put all the remaining channels in an ordered list in Favourites1. The TV list is empty in the Edit Channels>Edit Favourite List.
I assume I have done something wrong but cannot see what/where.
