Brightcove decrypt doesn't work

Hi - I am trying to download a copy of this:

From the network trace of the mpd file I see:

I have highlighted the relevant bits above and then put them into getwckeys.cc and it has produced a key:
a383a9cd22bb446b9f34c94fd92e3409:09a3d85004bf9ee7d 226d8d133c6cd13

I have downloaded the video/audio with yt-dlp --allow-u ... and ended up with two files of about the right size. However when I try to mp4decrypt them, the audio file decrypts to zero bytes and the video file to a similar size but still encrypted. There are no errors from mp4decrypt.

Any ideas what I am doing wrong? There is only another 30 days to make this work!

The key is good.
I have just used narrowine-reborn with my own CDM to download and decrypt and it works perfectly. Thanks for the link!
You might check yt-dlp -F to see which audio and video formats are available. If your audio file was zero bytes then choose another format.

If you cannot get it working the file is here:-

Oops, my bad. Somehow I managed to find a link and download a different video file! Now that I have the correct video, it decrypts fine. I've even got the .vtt subtitles working. It's a glorious concert, especially An Chúilfhionn (The Coolin) at about 19 mins in.
