### Region

France

### Provide a description that is worded well enough to be understood

Videos from https://www.college-de-france.fr/ used to be downloadable but they cannot anymore. There seems to have been a website redesign, which may be the cause of this.

Example URL is https://www.college-de-france.fr/agenda/cours/reproduction-et-demographie-chez-les-hominines/organisation-sociale-et-reproduction-chez-les-primates
