I have just changed from using Sky to BT TV and was wondering what is the equivalent of using the red button on the BT box for interactive services when watching BBC news 24?
If you have a YouView box, then the equivalent of the red button is... the red button!
It doesn't work on all channels. In fact, it doesn't work on most channels. The only ones on which it likely to do anything useful are the SD BBC channels. It doesn't even seem to work on the BBC HD ones.
