'Dave' is telling me to retune on Monday, and Al Jazeera is no longer available and saying retune to 235.
I've looked at http://www.digitaluk.co.uk/channels/channel_listings and AJ is still listed as 108, and Dave is still listed at 12.
There seems to be no info there or at Freeview about any changes (other than retunes in Bristol). I'm in London (on Crystal Palace transmitter I think).
Everything else seems OK, so I'm wondering how and when to change just these two channels manually, rather than mess with a whole retune, and where I can get info on changes if neither digitaluk nor freeview pages are telling me anything?
