"On the TV source selection button for the inbuilt tuners there are four options 'freesat', 'DVB' (Digital Terrestrial) , 'Analogue' (Terrestrial) and 'Other Sat'.
The 'Other Sat' option searches 'Astra 2 / Eurobird', 'Astra ', 'Hotbird' or 'All' satellites. You can remember about 1000 (if I recall correctly) channels, however as lots are encrypted for the
Sky platform (and other platforms I guess) there's little point saving these unless you have a suitable decoder."
Whether this is sufficient to nudge you in the right direction I cannot say as I freely confess to having no first hand knowledge of these beasties.
