From time to time if you watch analogue TV. We have one in our breakfast room. A banner obliterates the programme you are watching and reminds you that in April there will be on more analogue stations. This is fair enough, but there is no need to obliterate a tv programme. Why can they not do this over some in house tv promotions. I sincerely hope that when the Digital switchover happens in April 2012, that they put out more power on all of the multiplexes. We have a hill in front of our digital aerial, and ITV1 and other stations other than BBC show up as POOR SIGNAL. Digital TV is a flawed system, it needs a good steady signal. Cable and Satellite are the best bet by far.
