Windows 10. I can play the videos in Chrome and IE. I have read many posts, many 3 years old where people say they can play it, but plenty cannot. None of those posts ended in a solution. I'm hoping to find someone who's seen this before and fixed it or someone who knows how Opera works enough to point out the error of my configuration.
@leocg : my PC does not have Windows Media Player on it. It is Win10 Enterprise edition. Again, videos play fine on other browsers, so clearly seems Opera related.
