I've got the DirectTV HD package which gets me the standard HD channels, espn, Discovery, etc. But according to DirecTV's channel lineup I downloaded from their website, the networks are availible in HD for the East and West coasts. I get my local network channels from DC, and I know most, if not all of them broadcast stuff in HD. The problem is, I'm not getting these channels on DirecTV. Do I need to get them OTA or something?
