hope that is the correct term I just installed the Motorola HD101 ota stb in order to receive my local digital channels. On the FOX station, it takes longer for the signal to lock in & before it finally locks in, the picture is scrambled & blotchy. I have also noticed that the same type of thing happens when watching the channel. Just wondering what causes this problem. I live south of Louisville, Ky - 40165 zip code.
