What's up with this end-of-year glut of high-def channels? Seriously, it's like someone informed every cable carrier in America that it could get extra tax deductions if they hosted up a few more stations before the year's end -- not that we're complaining. Jason from Grand Rapids, Michigan has written in to inform us (and you) that eight new ones have arrived on his Comcast EPG. Biography HD (180), Planet Green HD (210), FOX News HD (214), Lifetime Movie Network HD (221), SPEED HD (223), FX HD (224), E! HD (225) and Cartoon Network HD (227) are all go for viewing, and all's that left for you to do is make it through the torrential snowstorms from work so you can actually watch 'em.
