A credible rumor is afloat that DirecTV has been down-resolving some of its HD broadcasts from 1920x1080i to 1280x1080i, most likely to open up bandwidth. Observers with sharp eyes may be able to tell the difference, even if only subliminally or unconsciously--something like Miss Clavel's intuition that "something is not right here." One of the channels apparently suffering from the new policy is DiscoveryHD, which ordinarily displays some of the best- looking programming available. Anyone notice D'TV's high definition getting softer?
