Fine, you've nerd-sniped me.

I tinkered with Dish Network descrambling 20 years ago. Not because I wanted to just watch a bunch of free TV (I hardly watched any TV anyway, we mostly watched DVDs from the video store and Netflix). More because it felt like an interesting rabbit hole. And it was pretty interesting!

I picked a good (newer!) satellite dish and LNB from the trash and had a friend help with the installation and alignment because that was his previous job. Normal people use some kind of tool to find the satellites' geosynchronous orbital station in the sky, but he did it often enough that he could simply look up into the sky and point at them.

There were a handful of grey-market satellite receivers you could buy that were technically capable of descrambling a commercial signal. Of course, they did not advertise themselves as such. They were marketed as FTA (free-to-air) DVB-S receivers. These were not illegal as they were fairly popular in regions of the world that actually _had_ a fair amount of FTA (unscrambled) satellite channels. The only satellites visible from North America, however, tended to carry religious, shopping, or Mexican/Central American programming. Oh, and NASA TV.

The receiver I bought had DVR functionality if you hooked up a USB drive to it. I think I still have some recorded shows on it. It would have been a great way to harvest and release pirated TV shows to the Internet, if you didn't mind editing out all of the ads and whatever.

DVB-S was basically a raw MPEG-2 TS stream that could be optionally encrypted. To use these grey-market receivers as descramblers, you install some custom firmware containing the descrambling modifications and keys. I'm failing to remember the technical details, but the encryption they used was not very good. Dish Network would rotate the keys occasionally, and when they did, you had to update them on your receiver. I can't remember now if the keys were part of the firmware, but I remember it being a pain in the ass.

The firmware/keys part of this had a very "colorful" community. You had to sign up to a very specific and somewhat exclusive web bulletin board in order to download the firmware/keys. I don't remember how I gained an account, but I remember it being non-trivial. IIRC, it was like one guy maintaining the firmware/keys and sometimes it took weeks for him to adapt to whatever thing DN did to thwart piracy. The board was moderated by a complete power-tripping asshat who enjoyed banning people for fun and then gloating about it. (I was not banned, that I recall.) I think they started requiring "donations" in order to view certain threads (like firmware releases) after a while. But I could be misremembering that. I just remember the community was very toxic.

After a few months of this setup, DN figured out how to rotate their keys too often for the casual pirate to keep up. I disconnected mine around that time and moved onto other things. Partly because the experiment ran its course and partly because migrating to real-time key updates would have meant buying a newer receiver. For a while, I flirted with the idea of getting a DVB-T PCI receiver card and working on breaking the encryption myself, but it was quite a bit above my skill level at the time and there did not seem to be anyone else working on it out in the open, since the DMCA was still pretty new then.
