Richard made a video a few years ago that he uploaded to Picasa. He has tried to burn it onto DVD and all he gets is a still image for the entire DVD. He tried to duplicate the DVD with Handbrake but he couldn't download it. Leo says to be sure to get Handbrake directly from Handbrake.FR. He'll also need VideoLan Media Client. They both work together to create the DVD.
Leo also says that Google transferred the video to Google Photos automatically when it killed Picasa in favor of Google Photos. So Richard should check his Photos account. Then he can download it and burn it directly.
The Chatroom says to right click the entry in Picasa and select locate. It will tell him where the original file is.
