Robbie,
Let's talk about tailgates!
The whole "local" vs the DNS is a very confusing area for many of us. And if you have HD then it gets even more challenging. We are just happy when we can hit the "bird"! Now we have the DVR receiver which is even more of a challenge...... It does not hook up with a coax like the old boxes! So we have to use an RF Modulator device. But... it is all good!
Later,
Dennis
