Provide a description that is worded well enough to be understood

This site features streams of public radio streams and podcasts using an embedded player.

Provide verbose output that clearly demonstrates the problem

• [x] Run your yt-dlp command with -vU flag added (yt-dlp -vU <your command line>)
