Maybe you need to call DirecTV, I typed in a McKinney zip and you can see WFAA is showing in the list. I would try unplugging the receiver for 15mins or so, and redo the full initial setup to see if that helps. If not, a call is in order.
update on problem....When I called D*, they had to push the channel again and it worked. I now get ABC(WFAA) in HD. Resetting the unit did not fix the original problem. Also, when looking at your channel lineup, the HD channels have the station call letters (ie "WFAA"), whereas the standard broadcast has the channel numbers.
I just saw this thread. I stumbled accross Channel 8 WFAA in HD because my off air signal was dropping out during game 3 of the MAVS VS HEAT game. I decided to change to the SD satellite signal and to my surprise it was in HD !
My question is ....why don't they let their customers know or did I just miss it? Also...when are the other locals coming?
