Strong feeling it's a kind of scam. I want to download an old 5min video of 1965, really basic and no HQ encoding at all, but I can't do it, I must install televzr. Ok, try it in a sandbox, want to test it so I decline premium payment. When I want to download, I got a message "You've run out of free downloads today, upgrade to premium" while I did zero download.
So I don't know if it works or not, but it's pay first, then maybe, it could work... No, thanks, I'll pass, given the low quality of the video, I'll use other mechanisms.

not working
