Video in Presenter 13: Plays in Preview, Plays After Published... By Jeffrey Dalto ...but won't play once I put it into a web page. I have a 13 minute video that I've imported in various different formats. When I attach the video, I then preview that screen and it works fine. I then publish the course and, when given the option to view the presentation, ,the video works fine. But then when i put it on our blog, as I've done many times in the past with '09, I get a black screen that won't play.Any thoughts?
