Advertisements Tonight my OTA tuner can no longer tune my local nbc and cw affiliate. I have rescanned channels twice and it still doesn't tune all of my local channels that it has been tuning successfully for the past six months. I moved the antenna cable to the tv and all of my channels are coming in fine. I have a decent 75 mile arial antenna on my roof and only live 30-40 miles from the transmitters on a local mountain. My in laws 40 miles further away are able to get the channels I stopped recieving. Guess I will give Tivo a call in the morning for a refurb under warranty.
