When trying to download a video from vier.be, the following error occurs:

When I try to view in the browser I get this message:

Maak uw gratis account aan zodat u deze volledige afleveringen kunt bekijken.
Met dit account kan u inloggen op zowel VIER en VIJF. Zo blijf je op de hoogte van de laatste nieuwtjes, kan je meespelen met onze wedstrijden en zelf reageren op onze video's en foto's.

Can you watch it in a browser without login with an account?

Now that you mention it, no, you need to login first. Woops. So, I've tried specifying the login credentials with -u and -p but it still didn't work. It gave the exact same error message.

Thanks for checking it, we'll need to add login support.

It seems there's a backdoor for retrieving the playlist bypassing the need for having to log in: https://bitbucket.org/basrieter/xbmc-online-tv/issues/809
