YouTube Embedded Sky News - sound but no video


I’m having a problem embedding YouTube Sky News Live. I appear to have sound coming out of the TV but no video, just a black screen on the YouTube video with spinning dots in the middle suggesting its loading. It works fine on the web preview from Xibo.

I am running CMS 1.8.2 and the player is on a Windows 7 embedded box.

I believe there were some issues periodically on Windows 7 and embedded YouTube streams ie per this topic Youtube stream cant find flash player 1.7.9/1.7.6

If you open the same stream link in IE11 does that loads correctly?
