I can probably download and decrypt the video and audio streams. But haven't done the research into getting the keys.
I'll try to see if I can find out how to get the keys.

There are 'tools' often sold here to download streams from popular streaming sites. I know those ones can print the keys for you with just a few minor modifications to the scripts.

It's my first time to use Telegram. I tried to send a message but it says both users must have each other in their contacts or something like that. I think I added you to my contacts. I sent a message 6 hours ago. I realize we may be in different time zones.

You have many different threads so I'm not sure which to respond to, but this one seems to have what I need.

I'm new to this and don't totally know how these cards work. Is it possible to purchase a card that we can recharge whenever we want? Or do we need to purchase ones with fixed dollar amounts and they have no recharge ability?

I don't know if there's any interest for this but offering to download videos available to prime members.
I'm guessing not much interest unless you seek video offered on Prime in countries other than your own, plus asking price would be as much or more than a one month prime membership probably.

5 USD per video downloaded

Had a successful transaction with no troubles. Thank you
