Hi Nicola,

It is possible to make Youtube only suggest 'More videos' from your own channel.  Here's how to do this in FreshDesk:

When editing the video page, you'll need to put it into code view, by clicking the the </> button on the toolbar.
In code view, find the src attribute which has the URL of the video.  
The URL should look something like https://www.youtube.com/embed/[videocode]

Just before the quote mark at the end of the url, add ?rel=0 (question mark rel equals zero)

Save, and now the More Videos will only show public videos from the Essential Resources channel.  

If there is already a ? in the url, then the change you make is different.
For instance, if the url is this:  https://www.youtube.com/embed/8Qpv_lR1bI0?wmode=opaque
Then, you add &rel=0 (ampersand instead of question mark), to get this https://www.youtube.com/embed/8Qpv_lR1bI0?wmode=opaque&rel=0

The rule is: 
If there is no ? in the url, then add ?rel=0 to the end.
If there is a ? already in the url, then add &rel=0 to the end.
