I think navigating the video-part of the website is inconsistent.
If for example I click on the latest John Watson video on “recent videos” I get to this page:
https://www.chessclub.com/videos/sharpen-your-chess-sense-with-im-watson-unconventional-16
But if I go to the videoarchive, and find the same video there, I get to this page:
https://www.chessclub.com/videos/webcast/icc/i/Watson/2015_06_09/Watson.html
And on only the latter of these, can I download the pgn file.
And I can find no easy way to get from the former to the latter page.
My suggestion is to fix this.
