Only "Published" recordings in the CAEN Lecture Recording Service can be watched by students (i.e. regular viewers). To publish a recording, follow these steps:
Find your recording in the list, and click the cloud icon in the upper-right corner:

Choose:
Publish to make the video viewable
Unpubish to make the video unviewable
Publish After to set a date when the view will publish
Click Update to save the setting:

You can also publish a recording by clicking Edit instead of the cloud icon, and changing the setting there - This also allows you to change the title and make other adjustments.
Note: It may take 30-45 minutes for the service to process a lecture recording before it is available for viewing.
