### Description of your *issue*, suggested solution and other information

Tried to download this video: https://www.youtube.com/watch?v=QL2CCeWZWQI and always get the "Could not find JS function u'ur'" error. I've updated to the latest version and that has not resolved anything. Other videos are downloading fine.
