I came back from camping a few days ago..and I also noticed that most of the HD channels were gone.
But I think they have all come back..this is what i got today.
4:1 CBS - Is back for me, looking good in 16:9, it was MIA for a while though.
9:1 NBC - Still has some dropouts although some days I dont get any dropouts..and its a lousy 4:3
15:1 (14)FOX - looks pretty good - 4:3
15:2 (14)FOX - I get the same "watching KFOX digital" card - 16:9
7:1 ABC - I got this channel back a few days ago, it looks good again - 16:9
(I can only get this channel on my VOOM HDTV reciever, I cant seem to get it with my RCA DTC-100..dont know exactly why?)
30:1 (13)PBS - looks good though its in 4:3
got a few other digital spanish channels but all of them in 4:3
