Just lately my Magic TV Box has been recording CH100 (which is nothing) when I have selected a program on TV1 to record in the guide.
I haven't changed anything in the last few years as it's been fine - CH1 is tuned-in and defaulted as CH1.
So the result is blank unplayable recordings - only for TV1. The other channels all record fine.
Has something been changed recently at Freeview's end?
