Hi, I have the same thing with mine. I have 2 digi boxes and 2 TVs with it built in and it's the same with all of them. 1 of the digi boxes is new and the other is 2 years old. The TVs are both nearly new, but they all have some channels missing and a couple that have got different names to the programs they show. I left it a couple of days after first retune then did them again but same outcome. Maybe in a week or 2 I will retune again with better results. I am in Devon and we been all digital for a while now.
