Help me downloading from serially.it

[jackfrost182]

Hi,I followed the instructions in this thread,but in the end I'm forced to ask for help.I'm Italian and I apologise for my English which is not my primary language.So here's the problem:I would like to download this video

https://www.serially.it/play/1303-la-paura-ha-inizio?t=0

,but the first obstacle is that in the . mpd file

https://redbee.serverside.ai/vod/mpds/9/970ee7e0-7014-4b9b-a312-6509e966eaef.mpd

I can't find/understand the pssh code to get the key.If I enter this command

N_m3u8DL-RE.exe --ffmpeg-binary-path C:\ProgramData\chocolatey\bin\ffmpeg.exe https://redbee.serverside.ai/vod/mpds/9/970ee7e0-7014-4b9b-a312-6509e966eaef.mpd

what I get are two separate files, video and audio, but the video has a black screen, the audio in .m4a format is not audible.What I'm doing wrong ?

Here is your file : https://www.swisstransfer.com/d/fdca42c8-6787-4503-b2ac-972f7ee611e9

I really appreciate the help with this quick reply, but I'm not a person who expects everything on a silver platter :I wish I could learn to do things myself. How did you get this link?I mean, the exact procedure
