Is the ~$5 fee for additional digital receivers purely a rental charge for the box, or is it a programming fee that would have to be paid even if I owned my own compatible digital box?
If it's just a box rental charge, does a purchased box have to be cablecard compatible to authorize/descramble digital-but-not-premium channels (MTV-2, BBC America, etc), or will anything that supports the right standard (DVB? QAM?), work for non-premium channels? Or some combination of the two (ie, not scrambling the bottom tier of digital channels, but scrambling the upper tier in addition to scrambling the premium channels)
