I am using Mr Mister's bouquets only I am missing some channels. And when I say missing, when browsing the channel list the names are not showing, isntead it says 'n/a'.

An example of channels I'm missing are the BT Sport channels.. If I go to the channel number it finds the programme information of what is on, but it comes up 'service unavailable. check tuner configuration'.

I must need to update something, somewhere but unsure what and I know this must be quite vague to the professionals out there
