I searched and didn't find anything exactly like my situation so here goes. Was adjusting the antenna and did a rescan of locals with my 722. One station has a new subchannel. It is found when scanned but will not show up in the guide. I tried to add it to the custom list I use but it is not in the list of channels. I tried to input the channel numbers manually and the tuner goes to the main channel. Main channel is 47-1, when I input 47-2 it just goes to 47-1. Not sure why it will not tune it if it was found during the channel scan.
