The instructions below describe how to modify a presentation's security permissions to make the presentation viewable to everyone.
From the list of presentations in your MyMediasite portal, select the title of the presentation you wish to make viewable to everyone. A summary of the presentation will appear.
From the Presentation Summary, locate the Who Can View? slider toward the bottom of the right column.
Move the slider to the position labeled Everyone.
Please Note: In addition to modifying the "Who Can View?" settings above, you should verify the presentation's visibility is set to Viewable so others may watch the presentation. A presentation set to Private visibility will only be viewable to the presentation's owner; others will receive an error saying the presentation is unavailable.
