I got my Roamio a few weeks ago. After running the setup, I was scrolling though the channels and noticed many missing. I went into the channel menu and found many were not check marked. So I picked all the ones I wanted to add. Now they show up as unkown for the channel name and no description for the programming. I have done dozens of connect to network and rebooted it too. How do I get these channels to show up like all the rest?
