Q: How can I see the rest of the videos from this event? There's only one video on the page.
You can see if it is a playlist from the bar at the bottom of the player (highlighted in the picture). Clicking on the bar will bring up thumbnails for the other videos in the playlist. Scroll along the thumbnails to select and play your chosen video.
When a video is in play, you can bring up the thumbnails by clicking on the icon on the video bar that I've highlighted.
I have chosen to use playlists where possible, rather than single videos, to reduce the load time and memory needed to open the pages.
