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

See [this video](https://drive.google.com/file/d/1ffdGgt-L0tuPs81NldvFFwoIifA421G7/view?usp=sharing) (which is part of what's downloaded from digitalconcerthall.com by yt-dlp) to see what I mean by distorted. Downloading the m3u8 link gives the same problem.
