I've gone through every help suggestion to get the videos to work. They show up as white, but if I click on the white space the video shows up for just a second and goes white again. I've made sure my antivirus program is disabled to see if that helped, but it didn't. Tried safe mode and it still didn't work so I'm pretty sure it's not a problem with addons or plugins. I have no problems with embedded videos in Chrome or IE.
