DirecTV in talks to buy Voom

We are all wondering where all these new DirecTV HD channels that they promised at CES are going to come from, is reporting that DirecTV is in talks to buy Voom from Cablevision. This would explain where another 15 channels are coming from, but still a far cry from the 100 national channels they announced. This seems a bit ironic as they actually made a crack at Dish for carrying some of these channels during their press conference.
