Although I use Freeview as my primary broadcast TV source, I have a Sony VTX-S760U Sky Digibox (though no longer a subscription) for the odd occasions when impulse interference from badly suppressed farm machinery disrupts DTT reception. I believe in switching things off when not in use but the problem with my Sony Digibox is that it loses its settings when power is interrupted, even briefly. It has always done this, but when I had just a 4:3 TV with only a PAL composite feed this didn't matter because they are the defaults. Now I have to reset to 16:9 and RGB every time I switch it on. I'd be very grateful to know whether anyone else has had experience of this problem, either with Sony Digiboxes or any other make.
