I was wondering if I were to use over-the-air HDTV signals to watch TV, Could I still use my cable box to just pay for HBO? Or what are usually the options? There seem to be only a few channels supported on over the air HDTV. Is there a more comprehensive list as to all the ones I COULD get in the San Diego area? I've tried a few sites, but most are very conservative as to what I am able to get as to ALL the possibilities. Has anyone else gone through this process? Is there a way to get the other channels on basic cable (i.e. TBS, History, Science and other basic cable NON-HD aired channels) through this same process? Or would I go through different steps? I just want to save money in the long run with making as few a sacrifices as possible, thanks in advance. Sorry for so many questions at one time.
