Which is better, hdtv with directv or comcast io cable? I live in New Jersey and used to have cable, I switched over to directv about 3 years ago. Now comcast is calling to try to get me back, they said their io cable is much better than cable use to be. I know going thru cable will be much cheaper than directv for hd. (no buying a receiver)Sometimes saving money is really worth it, if the picture isn't as good. Is one of these brands hd quality better than the other? Any help would be great.
