Challenge for you! Get streaming File

[Jonix96]

Hey folks, I have subscribed to an official site where I can watch full motorbikes races.
Anyway I would like to get some of them for me, because my subscription only lasts some months, I want to keep them.

I tried extensions for mozilla and chrome, but I only get to download always a 2Gb file at 170 Kb/s, no matter if the video is 4 minutes or 50 minutes.
I think this is weird.
NetVideoHunter let me reproduce the video, but when I download it it's always 2 Gb.
I can inspect the element and find teh id of the video I want, but I don't know what to do with it.

Also I got this infos, not sure they are important

This is the file I get with every extension:

subscription / rental services cannot be discussed here
because it violates copyright laws.

They could discuss in private perhaps?
It's for private purpose only, no copyright infringment.
I would watch them offline
