Why do I get a black screen with audio still playing out in the background when I am watching a programme?

All 4 application automatically detects the best available bandwidth to play out the most suitable quality video/audio format. If you are in an area with low Wi-Fi connectivity, the application will detect this and send a lower quality video stream and an alert message is displayed to indicate the connection is running too slowly to play video. As soon as the application detects you are in an area with better Wi-Fi connectivity, a higher quality video stream is transmitted.
