My box was on standby all night and the next day so should have reset itself - BUT I then even did a manual retune which also did not sort the problem. I then when I saw Huevos's comments which made me think that the update had not worked I tried the factory reset- and then that did work. SO it means that for some reason these particular channels did not update themselves but were tuneable only when the box was effectivly wiped and rescanned - but why?
As stated, most Freesat only receive updates at " silly o´clock " when in standby mode. A re-scan on existing incorrect software would produce no change. Only if the box correctly received the updated information could it see the FEC changes, thus " miraculously making Pick re-appear "
The Sagemcom I have is limited in it´s " non Freesat search ". It only allows to search on FEC 2/3. I e-mailed Sagemcom about this and was told, that´s how it is! It would appear they don´t care about the box´s limitation.
With regard to the why " these particular channels did not update themselves but were tuneable only when the box was effectivly wiped and rescanned " , back to software version. I assume the Humax, loading from default, checked for software updates in background, updated, then re-scanned, producing the correct result.
If this is not the answer, I believe you may have a poltergeist in the Humax, very painful and possibly expensive to fix!
