I also live in McKinney and can certainly relate to your problems getting the Fox HD channel. Compared to the other local HD channels, the reception on Fox is by far the worst I have noticed...constant picture and audio drop-outs although the reception is no better or worse today than any other day. The picture is typically so bad that I'll watch and record Fox programming using my OTA antenna. It's not perfect but better than going through the Dish. Let me know if you ever find a fix for this.
