I very much agree with all that has been said on the confusion caused by the switchover, after having another read of the booklet that came through the door a couple of months ago, it does not cover a lot of issues with recording equipment, I had to explain to one elderly neighbour that her video recorder needed it's own freeview box to enable it to record one channel while she watches another channel via her original box.
Since posting earlier, I was called to retune another box, unfortunately the remote has been lost, it was being used via the channel up/down buttons on the front panel, I have replaced it with another box I had spare.
If anyone has a remote for a samsung SDT-7000, please PM me.
