Cable One makes some HD channels viewable only with CableCARD / STB

At first glance, we assumed that Cable One had relegated a number of channels to switched digital video, but that doesn't appear to be the case. Instead, company officials have proclaimed that "cable programmers like Discovery HD, Nat Geo HD and ESPN HD have requested their signals to be scrambled," meaning that subscribers will now need to fork out for a CableCARD or cable company-issued set-top-box in order to see all 24 high-def stations offered in Sioux City, Iowa. Ah well, you've been looking for a valid reason to make the leap to a carrier with a real dose of high-definition anyway, right?
