The trailer fails as well so it looks like a fix is needed. Or do you want a workaround. You see the 3 dots button beside download.
Click that and go down to details. Click this to see more information. Copy the main url and paste in a text editor.
Look at the link where you see master.m3u8 , replace m3u8 with mpd after which copy and paste in a new tab page.
There should be detection and the download will work.

Thanks for this! I did see the link with .m3u8 extension, it looks like this:

https://video-cf.stage-plus.com/DEA282155319/master_1920x1080p25_h264_qvbr9_mpassHQ_gop4s_4680k.m3u8

Replacing the extension with mpd and access it in browser give this error:

<Error>
<Code>AccessDenied</Code>
<Message>Access Denied</Message>

</HostId>
</Error>

These videos need a subscription to access, so perhaps there is some authentication problem.

[Mattmjs]

I think you used the wrong link, the link I already mentioned should be master.m3u8. It shouldn't be the video component but
the main url. See the screenshot

Thanks for clarification, I tried opening this link with extension replaced in a new tab but an file in XML format is downloaded automatically:

Ok maybe it does that because as you said a subscription is needed to access videos. It did work on the trailer but that's different
to what your accessing. Maybe using edit and resend in the developer tools could do it. Other than that you've got it in ffmpeg.

[sghng]

For reference, I found this command works for downloading:

ffmpeg -i "https://video-cf.stage-plus.com/DEA282155318/master.m3u8?token=<token>" -c copy -bsf:a aac_adtstoasc "output.mp4"

My assumption is that this browser extension doesn't pass parameters when downloading the video.
