No, it's not their fault. There is absolutely nothing in the HDTV standard that syncs audio and video together. It is a flaw in the standard that was set back a dozen years ago. You have just found this flaw first on DirecTV. Others of us found it first on cable systems or broadcast. Should we blame those media providers just like you blame DirecTV? Seems short sided to me. You're blaming the cup for the spoiled cream you poured into your coffee.
