since the digital switchover i have had a probelm retaining my channels, I receive signals from the sandy heath transmitter. After the first stage I kept losing the BBC channels and every time i switched the tv off i lost them and had to re-install, after the second change the BBC are ok but again when I switch teh tv off i lose the ITV stations, after trying the manual install which failed I have had an email chat with the digital helpdesk who tell me there is a software 'issue' with the 5522 model. Any other users expereienced this?
