Brian , we've just had ITV1+1 . It has gone onto channel 33 and replaced ITV2+1 . Does this mean we have now lost ITV2+1 altogether . I've tried scanning for channel 27 but cant get it .

Wayne- As porth is a relay, you have lost ITV2+1. This channel has moved to MUXA, of which you cannot receive, I'm afraid.
