I just got a digibox - the Panasonic TU-CT30, and have been having some weird problems. Basically, half the time C4, ITV1/2 and C5 don't work at all - just says 'bad signal'. Then other time they work fine, signal seems not a problem. All the times I've got it good again seem to be when I disconnect and reconnect the RF stuff (to check I didn't mess it up) - it seems to work again, only to stop working later on. I only got it today so don't know what the real pattern is. Could it be a dodgy box? I'm rather confused.
