Hello

Thank you for your answer.
I can find the mpd file, however i am unable to lacate the method to use the key you provided in the yt-dlp manual.

It was also my mistake to provide a video example without subtitles.
This is a better example where i was able to locate a vtt file but get an error when trying to download it.

Any help is very much appreciated.

yt-dlp doesnt support decrypting, so you could download video and audio with yt-dlp, decrypt each part with mp4decrypt and then join it, or you can use N_m3u8DL-RE as iamghost mentioned which does it all in one command.

heres the link to the subtitle file that i found for your link.
https://www.rtve.es/resources/vtt/4/5/1512337755154.vtt
just paste the link into any downloader or browser window and it works - no special headers etc needed.
what error are you getting when trying to download the vtt?
