I just started watching Pages from Ceefax on our Freeview receiver and wondered if it was on iPlayer.
I went to the BBC 2 page on iPlayer and it said 'ON NOW: Fimbles, 6:00am - 6:20am' even though it was 4:20.
I put the streaming version of BBC2 on, and I was surprised to see that the BBC broadcast the Pages from Ceefax programme on iPlayer. Although the programme's name is not mentioned.
Also, the Ceefax page shown in the screenshot is one which is well over due :).
