Do digital cable boxes broadcast DD 5.1 sound? I have one and the most i have seen is DD 2.0. Is it only with movie channels? Any other channels? I read that this year the Super Bowl will be broadcasted in DD 5.1 and am wondering if i can get that. I dont think i can because it seems that not all the channels on digital cable are broadcasted digitally(all the basic cable channels). I would switch to satellite but i have too many tvs. anyone here have adelphia digital cable with Scientific Atlanta 3100?
