I received the following on a postcard from Sky today:
On 10th December, Five is making some changes to its service in your area.
You will still be able to enjoy all your favourite Five programmes, but as a result of the changes Five is making, any programmes you have set your Sky+ or Sky+HD to record on Five from 10 December will not work. To make sure you don't miss any favourites like Neighboursand CSI:Miani, please go to your Sky+ or Sky+HD planner on the afternoon of 10 December, delete your planned recordings on Five and re- select what you want from the TV guide (including any series links).
Not sure if it will apply to everyone, or just those whose cards were activated in the Yorkshire region.
