### Region

United States

### Provide a description that is worded well enough to be understood

When trying to download a public video from WGBH Boston ([WGBH video](https://video.wgbh.org/video/episode-1-3fjvai/)), it reverts to a generic extractor, resulting in an error, even though the video FQDN is included in the PBS extractor (currently line 65).

### Provide verbose output that clearly demonstrates the problem

- [X] Run **your** yt-dlp command with **-vU** flag added (`yt-dlp -vU <your command line>`)
- [ ] If using API, add `'verbose': True` to `YoutubeDL` params instead
- [X] Copy the WHOLE output (starting with `[debug] Command-line config`) and insert it below
