Why do I get audio but no picture when I'm watching All 4 on my iPad, iPhone or iPod Touch?

The All 4 application on the iPad, iPhone and iPod Touch 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 (nb: older versions of the All 4 iPad application do not display this message, simply a black screen. We recommend that you upgrade to the latest version of the iOS or app). As soon as the application detects you are in an area with better Wi-Fi connectivity, a higher quality video stream is transmitted.
