Got the Nomad this week, and every evening when I come home from work, it only shows one or two shows from both my DVRs. I have to power-cycle the Nomad, and then all the shows from both DVRs appear in the list. Next day, I get home from work, and the same two or three shows are the only thing that shows up in the list. I power-cycle the Nomad, and all the shows re-appear. All this while this is happening, the Nomad shows three happy blue lights. What is wrong with this thing? Do I need to return it?
