My Cox provided CBS HD signal was up to its old tricks during the Super Bowl; I had the audio cut out maybe a dozen times during the broadcast. No problems between the broadcast and commmercials, however. Looks like I will make a call to Cox to see what they can do to fix the problem. I expect I'll go through a couple of iterations with them because my past experinece has shown their field techs are not that savvy. Hope everyone will keep eachother posted on their results with their HD providers.
