After slowing its pace of adding HD channels dramatically as of late, DirecTV has finally satisfied one of the loudest and longest running customer requests by announcing AMC-HD will come to its satellites starting September 9th. There's still a pretty long list of channels it's not offering yet, but if you're on contract and just want to enjoy someand(when it returns in March) in HD then today's Facebook posting (just hours after it was dug up by the satellite sleuths at) is exactly what you've been waiting for.[Thanks, Joe & Casey]
