I think directv will have a big problem over the next few months. They promised all these HD channels and assumed that their outsourced installers where properly installing the systems. Now you have all kinds of average folks with diplexers, etc installed in their homes and are not getting the proper signals. I spoke with about 10 co-workers and friends that have this problem tonight! A few have the h20 and are getting none of the new channels and have been on the phone all night with directv. If directv does not quickly figure out an easy install, single wire solution that can be done by the do it yourselfers, the increase support calls will sink the install companies.
