On the 27th September BBC HD channels changed frequncy, if you are using a sky box you should not have noticed a difference.
However If you use a Freesat box or other free to air receiver you may need to place the box in standby for a while and then back on.
If this does not solve the problem then a Freesat channel retune will be required.
Please refer to your user manual or go to www.freesat.co.uk for further assistance.
