Go back and read the first few pages of this thread.
Basically it's to do with the Freeview part of the box. A reboot fixes it for a while, as does disabling the Freeview addon.
I have the FreePlus setting switched off. So it can't be that.
Well I tried the reboot and it appears to have fixed the issue. What a PITA!
