Well, yes, but that doesn't mean the CATV proivider is required to. They can send anything they choose out in the clear. Indeed, while I haven't noticed them doing any such thing in the last couple of years - not that I've paid attention - some CATV companies will host subscriber campaigns designed to get subs to add pay channels by disabling encryption for a time so everyone gets certain channels for a short time for free. Edit: Note San Antonio, like Austin, encrypts its SDV channels - although I haven't checked them all I would presume all of them. The only thing you might find is an occasional video rewind stream where someone watching one of the locals on an STB presses <Pause>. I don't know for a fact, but I wouldn't necessarily expect on-demand content spawned from an unencrypted source to be encrypted.
