Hi Deany123
If the remote appears to have stopped working wiggle it a few times. You should also make sure that the Power Saving mode setting is on Fast Start
Have you tried the red button on other Sky Sports channels? The additional red button content on Sky Sports+ is also available on the other Sky Sports channels with the exception of Sky Sports News, Sky Sports Mix and Sky Sports Racing.
Make sure it is the red button at the base of the remote that you are pressing and not the red record button.
Do you have the red button issue on all BBC channels or just BBC1?
The box needs an internet connection for the red button to work. Do you see any onscreen error messages such as CS2400 when the red button fails to work?
When the red button fails on BBC channels try hitting the back button on the 360 remote if the error message appears, and then press pause and play
