We have .mov files that are published in several different presentations, with each presentation playing on a different display (Berkeley, Chicago, Toronto). The videos play on all of the displays except one (Toronto). I have tried to play a working presentation (Berkeley) on the display that wasn't playing videos (Toronto) and it wouldn't play. I tried playing the Toronto presentation on the Berkeley display and the video played. The Toronto display is using the latest Rise player so I upgraded Berkeley to the latest Rise player. Now neither play video. Any suggestions?
