Ever since AT&T decided it would take its U-verse service to the chilly region of Northeast Wisconsin, Time Warner Cable has been pushing out a somewhat steady stream of high-definition channels (big surprise, right?). Now that a few weeks have passed since residents in Green Bay / Appleton received their last batch of newcomers, the carrier has lit up four more: CNN HD (731), Fox News Channel HD (745), Science HD (772) and Hallmark Movie Channel HD (774). Now, if only this whole Brett Favre thing would go away, you could actually turn away from ESPN HD long enough to enjoy 'em. [Disclosure: Engadget is part of the Time Warner family]
