Embedded videos Playback issue
I hope you can help me on this one? I've published some elearning content that contains an MP4 video embedded within it. The content all loads fine but on some systems the video plays and on others it is just a white screen and doesn't load. To make this even more interesting, the same systems that won't load the video in one LMS (Cornerstone) will load it (video included) completely fine in Moodle... And in Cornerstone there is a pre and post published state - in pre publish the content is fine and all loads, but in post publish the video doesn't.
So, my question is this: Do you think that it is a problem with the elearning content, the IT systems we are using or with the post-publish section of the LMS (Cornerstone)? Has any-one else experienced this before?
