You might hear a short (30 second?) pre-recorded message before the start of a programme, which says something along the lines of:
Windows Media Player is not going to be supported anymore and at the end of the year your device will no longer be supported. You should contact your device manufacturer.
This is news to me. I am investigating possible fixes.
In the meantime, I understand that once the announcement has finished playing, the normal programme starts to play as expected.
