Can you watch it in browser in the first place?

[Wuzzy2]

No, I don't have Flash Player installed, and I don't intend to install it.

By the way, youtube-dl managed to get southpark.de videos previously for me. It just recently got broken for some reason.

I'm unable to play this particular video from southpark.de in browser, so I'll treat this as not youtube-dl issue since you can't confirm.
