I noticed today that You Tube video URLs are working again with the Video Gadget. Why are they working now and they wouldn't before? I thought every video had to be HTML5 based to work in Rise. Am I doing something wrong or did You Tube change the formatting of videos to HTML5 now?
It looks like youtube did change their format to HTML5 some time ago. Keep in mind that this is unsupported use of the gadget/widget. If you want to display youtube videos, I would recommend the Youtube Widget by Scott's Digital Signage to avoid any problems.
