I'm a former TWC user only now trying to understand how things work. I've read that their "Standard TV" service comes right in on analog alongside the "Basic TV" service. According to their lineup page, a set top box is only required for a few HD Standard channels. So if you subscribe only to Basic, how do they stop you from looking at the 40 or so analog Standard channels?? It can't be scrambled, right? I don't think they can scramble to individual customers on a node without scrambling to the whole node. (If I'm wrong in any of these assumptions, please correct me.) So then it must be filtered. Do they REALLY come and slap a filter on the line every time someone cuts from Standard to Basic?? Really seems very inefficient.
