digital cable descramblers

My Mom's ex-fiance used to use something kind of like this.
He had a pc, a box with a card in it, and once every month he had to get a new floppy disk for the pc, with new codes or some shit.
He got like channels 100-200 (pay-per-view), and up to channel 900 (most were triples though.)
This was of course before I literally threw his virgin (self-admitted that he never had a girlfriend in his life) 24 or 25 year old scrawny ass punk kid(who still lives with his dad) into the whole setup (including the Mitsubishi big screen) for threatening my little sister and my Mom with a Police Baton.
Best moment of my life, I was laughing my fucking ass off at him, all bloody and shit.
Then of course his Dad(who was calling my sister and mom bad names and threatening them) came charging at me so I took a defensive stance (left leg behind right, my right shoulder facing his direction and bracing arms in a flexing position) and he ran into me and fell on his ass (I pushed back a little).

Anyway that is off topic, but I just get worked up every time I think of them, with him stabbing that baton at my Mom and little Sister (I was inbetween them).
But uh, yeah, in short, they had one of those kind of, but for satellite and it was cool except once a month for a few days the tv would work for a few mins then freeze for 1-20 minutes, which was a PAIN IN THE MOTHER FUCKING GODDAMN ASS during the Super Bowl. I dont know if Digital is like that, but I dont think it is.
Just stay away from the satellite ones.
