Have fixed this by doing two things...
- setting up a redirect so you should now NEVER see the "insecure" site warning in the browser address bar.
- editing a few of our site templates to make sure there are no static links to HTTP things
Let me know in this post maybe if you notice any related weirdness, for now tho videos should be all good.
Thanks to Eagle-Eye Charl for spotting the YouTube issue.
