Hmm, just tested something out, but the embed option using the given code in YouTube doesn't show properly (just shows the link). It would be great if in the details of the event it could have a video feed as well.
Got it. Realised after +John Barwick showed his screen shot, and was different to mine. By default the advanced fields do not show. Under Event Options select Advanced Now add the embed code that you get from YouTube. It works. Thanks +John Barwick
