Hi @Rixydix, think Auto Tuning is best unless there are any issues and you can transfer a channel list via USB but do have Freestat (however principle much the same as Freeview-though do not have the need to use that much )
As far as Tv settings go much the same whether you are using Freestat/Freeview or satellite/cable system. Generally it is best to use Movie or Standard Mode, keep auto processing to a minimum and disable most of the Eco settings to give a brighter picture. There are various expert recommendations available but to suit your own preferences a bit of tweaking may be required. Personally whilst I don't have the same model prefer the backlight to be a bit higher than is generally suggested.
