I’m having trouble on Versions 1.4.7 and 1.5.0 with playing video on slides. It was working previously, but today I’ve been adding more videos and more picture slides and now my videos sometimes show up as just black, sometimes show up as a big video icon, sometimes show up with no sound, and seem generally unreliable. I have tried rebooting the player and the server. It seems that it works fine when I play it on my laptop as a monitor, but I can’t get it to work on my player. What can I do?
