Short: This sux.

This has large implications for users that have HTPC's hooked up with QAM based capture cards so they can get live TV into their Media Center PC's. With this new change, I think all of their hardware will be useless. They will have to buy new cable card tuners like the Ceton and Homerun Prime devices to get this content (and pay a cable card fee).
Cox has only had the local channels available over open (unscrambled) QAM for the past few years, all the other digital signals are scrambled. However, they still provide channels 2-74 over analog, so I can plug in an old TV & receive all the channels.
I have a HTPC with a older analog/open QAM dual tuner and a Ceton 4 channel cable card tuner. Never have to worry about recording conflicts since we can have up to 6 channels recoding at once. The single Cable card fee is a reasonable $1.99, a lot cheaper than cable boxes. Biggest problem was getting them to get the card registered in their system. correctly.
