Auto Tune to HD not working for all channels - Contour2

I have the Contour 2 box.  One of my favorite things about the Contour 2 is the auto tune to HD.  I don't have to go through entering all the 1000 plus numbers each time to get to HD channels.  However, one of the channels doesn't work.  I'm in Phoenix and the Big Ten channel 320 does not auto tune to 1320 as all other channels do.  

Can someone at Cox look into this and get it updated? 

Thanks!
