In recent weeks they've started inserting interstitial ads for other BBC content at random points inside In Our Time.

"How can they do that, the show is an uninterrupted 45 minutes of talking" you might ask. Well, they just insert it at a random point somewhere, possibly halfway through a sentence. It's both very annoying and amateurish.

I don't know if this applies to your circumstance, but w.r.t. those m3u8 urls posted elsewhere: I have found that a lot of systems will cheerfully reference the ad-break content on some rando spammy looking domain in the middle of their otherwise sane #EXTM3U format making it cheap to just block them and the player skips over it

My suspicion is that is how uBlock Origin is able to make the YT ads magically disappear without otherwise blowing up the content stream
