A few years ago the U.S. government made a law that people can own their own cable boxes (when all service was analog). Does this apply to non-HD digital cable boxes in use today? My cable operator says "no". Is that correct? Some of the channels I watch have moved from "Extended Basic" to "Digital" Tiers even though they are not in HD. I don't want to pay rent every month for a cable box. Must the cable operator allow me to buy my own box? If so, where can I get one?
