Why won't Cablevision add Sundance HD? Cablevision used to own Sundance (bought it from Hollywood icon Robert Redford) as part of Rainbow Media before splitting it off as part of AMC Networks. Cablevision still owns a financial stake in AMC Networks and Charles Dolan (Jim Dolan's father) is chairman of BOTH Cablevision and AMC Networks. I just don't get it! This doesn't make any sense!
