Freeview viewers throughout Wales must re-tune their equipment in order to continue to watch S4C from 9 September. The Welsh-language channel will be moving to multiplex 2 on that date, enabling those viewers who only have access to public service broadcasters' channels to watch, whilst also keeping room on multiplex B (its originally-planned home) for planned HD services. The move should also create space on multiplex A for Discovery's new channel, Quest.
