Wistia IFrame embeds not detected

On this page: http://humanisetheweb.com/videos-london-2015/

The videos from Wistia are not being detected correctly. Only one video is picked up, and when downloaded (4.3GB) it played for 1:58 and had audio only (tested in VLC and Windows Media Player).

A full transaction is:

If I give the embed URLs manually to youtube-dl it works fine.

@thomasrussellmurphy, not the same issue, this issue is about not downloading all Wistia videos in a webpage(only the first), your issue is an embed not picked because the Wistia script is not loaded directly in the webpage(loaded from another script) which will cause this part to fail.
