au regard du retour 
HTTP Error 403: Forbidden
je te suggère de lancer dans un terminal 
$ man youtube-dl
et d'étudier la partie "Authentification options" et éventuellement "Workarounds"
[justify]Tu lancerais quelle commande ? Je suis un peu perdu pour être honnête.[/justify]
[justify]
[deviennenicolas@localhost Saison 1]$ sudo youtube-dl -U
[sudo] Mot de passe de deviennenicolas : 
It looks like you installed youtube-dl with a package manager, pip, setup.py or a tarball. Please use that to update.
Que/Quoi faire ?[/justify]
Mais c'est écrit : Please use that to update.

j'essaierai avec les paramètres -u et - p, suivis respectivement de ton nom d'utilisateur et de ton mot de passe (ceux du compte associé au site, pas ceux de ta session sur ta machine)
et en essayant avec l'option "--user-agent", histoire de faire passer youtube-dl pour un simple navigateur ?
[justify]Tu le places où "--user-agent" ?[/justify]
