so i have been playing around with media and it seems to be limited to just youube as the videos that are blocked can be seen from daily motion or vimeo..the only vids that are working for youtube are those that dont have a high copyright claim attatched to them,,however 7 weeks ago we could not use daily motion or vimeo and they have since started working again and one or 2 videos would not work on youtube have started to play.. this could be something that will fix given time tho can not garuntee it
