Your comment caught my eye, mjs. So I tried looking at that site. It was telling me
something that, in my practically non-existent understanding of Italian but by analogy to
my good understanding of French, I was able to figure out that it was telling me that I
had to have a subscription to Eurosport & be in Italy to view the content. So I enabled
my VPN & told it to pretend I was in Switzerland, the closest it offered to Italy. Poof
magic, suddenly I could see things. I picked this item totally at random:

It's only 23 seconds long, perfect for a test. VDH had no problem downloading the video.
The audio was a different story. When I first tried getting the obvious audio variant,
the one you pointed out, VDH errored out with its usual M2TS error message. So I did the
ususal, enabled HLS as M2TS in the VDH Settings. VDH was then quite happy to download
the audio. It claimed to be 23 seconds long. I played the video & audio synchronously
in VLC & it started fine. But then 5 seconds in, the audio stopped. I tried downloading
the audio several times, after reloading the extension & reloading the web page. But the
thing stopped after 5 seconds every time. I played the .m2ts file directly in VLC. You
do know you can play .m2ts files in VLC without doing any strange conversions. But
despite VLC claiming it was 23 seconds long, it stopped at 5 seconds. I don't know what
the deal is here.
I did the usual trick of looking for a manifest in the Network Monitor. There was what
appeared to be a master HLS manifest but ffprobe choked on it with 403 Forbidden (access
denied). Playing the video in the player on the web page gives the full 23 seconds of
audio to accompany the video.
I give up. This one has me stumped. At least I learned that I can get into Eurosport
Italia via VPN set to Switzerland.
