By direct publish to ReviewLink, are you referring to publishing from Lectora? CVR doesn’t have a ReviewLink publish which threw me a bit off there.
Lectora actually just uses an HTML publish for its native ReviewLink publish, no SCORM 2004 involved. A SCORM1.2 publish (or 2004) is just a wrapper in how the course sends results to the LMS, so again, won’t affect how it sends video to the browser.
So, I have to say it…. sounds like a coincidence….
