@ejstubbs, oh I understand that choices need to be made. Did not realise the BBC were restricted in that way - odd because on the first full day of the Olympics they had BBC1, BBC2 and Red Button but I cannot recall if they were all showing different things, maybe not.
Perhaps I'll just need to be happy that I stumbled across a few events that I wouldn't have known about otherwise. I shan't be forking out for a Discovery+ subscription just to have access to (presumably) everything...
