Downloading

Of course you shouldn't download illegal content, nevertheless, as content providers don't keep everything online for eternity, keeping an offline copy for yourself sometimes is your only option. I particularly like the Belgian VRT archive content, which they always temporarily release on the site, and can't even be found on dvd or streaming services...

Downloading from their archive isn't easy, and you need to adapt from time to time, but at least there's a way to do it... What should work on multiple websites is opening the chrome developer network tab, and looking for the mpd references. Opening these in VLC and converting them to file with original audio & video streams should do the trick.
