emma – we digitally switched over ages ago. before the switch i already had a freeview box and was happily watching all manner of rubbish when one day some channels went missing. with less rubbish to watch, i watched less tv, so no bad thing. Over the next couple of months, the tv would tell me it had found new channels and ask if I wanted to retune. if I said yes, it would retune itself and take away another couple of channels. eventually, i was down to E4+1 (but not E4), BBC1 and 3, and some shopping channels. most of the radio stations went as well, which is when I discovered Internet radio.
then the Big Retune day happened, and most of them came back.
then a week later there was a second retune, and the rest came back.
so retune every so often and relax, technology knows what it’s doing.
