Was running late with the braai this weekend and missing the rugby build up to rigged up an old tv to Apple TV and mirrored by iPad like I have done so many times before. HDCP error. Panic. All the google threads said switch off, switch back on, reconnect cable. Not very scientific and none worked. Finally discovered it’s a DSTV app problem. If you mirror your iPad first and then open DSTV you get this error. The trick is to open DSTV first and mirror from within the app. Hope nobody else misses rugby due to this error message
