As mentioned a few days ago, if you have not retuned your set-top-box yet, you are recommended to do so as soon as possible. Whilst your Freeview box will still receive digital terrestrial broadcasting using it’s current configuration, for it to perform at optimum viewing quality rescanning will refresh the channels your television benefits from. Good advice is to do this every month or so anyway but on this occasion the advantages certainly outweigh the couple of minutes this will take.
