Yesterday I was moving things around near the tv and cable box. First, there wasn't any audio. So I kind of nudged the ball of cords and the audio started working but then I couldn't get a feed on "Cable" on the home screen. I checked all of the cords and everything seems to have a tight connection. AND I can get the cable feed via the A/V module on the home screen, so I know the cable box is talking to the Roku TV. But why isn't the cable feed reading out in the Cable module on the home screen? A/V doesn't give me a full-sized screen and it doesn't appear to be HD like Cable is, so I'd really like to get Cable working again.
