OK. Here is the problem. I have a SCI ATLA 3100 cable box and when I put HBO channel 500 one of my favorites, I can't get the channel. In fact I can only get 2 digit channels. To get HBO, I have to manually type in "500" on my cable box /numbers setting. Also, when surfing in favorites mode, the up channel button only goes to the next favorite, not the next actual channel. How do I fix this?
