I have a directional antenna and when I do the automatic "Channel Scan" I do not get all the HD channels that are supposed to be in my area because the antenna points in one direction. I don't see any way to add digital channels manually. You can add analog channels by checking them off on the "Channel Skip" screen, but there doesn't seem to be any way to add a digital channel. This is too basic a function to have been left out, so it must be there somewhere. Anyone know the secret?
