Afther 'processing' , the lines youtube-dl in goes to 'error' 0%
I tried to "return to an old windows recovery point" - didn't changed anything.
Downloading from youtube still works, so i don't think it is a problem with youtube-dl. (it was smarter to first test, that one, I know).
Video's that worked in the past (1 month ago) can't be downloaded now.
The side 'Ketnet' changes it videos reguraly (weekly), so i used a link that is there fore multiple weeks to demostrate.
The side 'VRT' (family-group of Ketnet and Canvas (also mentionned in error-repord) had in the past a change that not all the video's where working anymore, so i think it is a setting of the site that is tranfered from one site (VRT) and now also used on the Ketnet site as well.
(VRT you have to create a log in, for Ketnet you don't, so i used the Ketnet site in this example problem.)
The example is a 'sort -10min video' example (Sisters) or 20min (smurfs)

A smaller one (5min)  is on "https://www.ketnet.be/kijken/g/grizzy-de-lemmings" but the end changes reguraly: 'https://www.ketnet.be/kijken/g/grizzy-de-lemmings/1/grizzy---the-lemmings-s1a40-construction-bear' so probably it won't work when you read this.
