I notice from my TV that the 'almost weekly' alteration and addition of channels is upon us again. Seemingly only Sky Three and Sky Three Plus 1 renaming themselves as Pick Tv, and 'Daystar' on channel 47. If I run a complete retune of my Humax, will I lose my existing timers? I can't find anything in the manual about this, and am not sure about the manual tuning instructions. Would one way ahead be to take down the channel/frequency details of Sky Three (and +1), delete them, and then get manual search to find them again?
