Make sure you are viewing ALL channels and not a custom list. If you are in a custom list just add them. If you are in the ALL list and they do not show, try resetting your box or unplugging it for a few minutes and restarting it.
I checked all versus custome list and all the HD channels are in custom. I did the reset and still don't have the 2 channels in the guide list. Very strange. Any other idea? Do you have an HD10 also? Can you see all channels correctly in the various guides?
Tried everything you guys recommended so far, without success. Still do not see all the HD channels into my "guide" screen. Strange. Anyone knows if there is an engineering menu to configure the "guide" profiles?
