I'd recommend signing up for a VPN in order to get around region blocking, and watching whatever the public television sites in Germany, Austria and Switzerland make available for free streaming online. Or, if you like podcasts, just switch to German-language podcasts. That's how I keep my French brushed up, and it works a treat. FWIW, I think the same works for Esperanto. I don't speak Esperanto (yet) so I don't know their quality, but I looked into availability of media recently because I've been thinking of learning it, and it seems that there are plenty of podcasts in esperanto, and even some international news services that do a regular program in esperanto. Not anywhere near as much as English, of course, but it looks like plenty enough to keep a body entertained on the way to B2 level or so.
