I don't know if you still can do it or not but sign up for the distant locals on AAD. I currently have the NYC ABC and Fox channels because the quality is much better and you also get more sports. The ALC series and the World Series were not on the Fox channel from PR last fall. You also get the late afternoon NFL games which sometimes the VI/PR locals don't broadcast.
At one time the AAD channels from Chicago were in HD, but they are no longer available.
