In Phoenix, the local ME-TV affiliate was mapped incorrectly. DirecTV refused to correct it because it was a low-power affiliate. This is an odd situation... 7.1 broadcasts on 7.1 in Prescott, AZ and 36.1 in Phoenix AZ 7.2 broadcasts on 7.2 in Prescott, AZ and 36.2 in Phoenix AZ For two years, 7.1 worked fine on the AM21/HR20 but 7.2 would not come in. Complaints to DirecTV fell on deaf ears and I gave up a long time ago. I noticed last night that 7.2 is now fixed. It automatically corrected itself on my HR20-700. I had to reset my settings on my R21 box. I have a H25 with an AM 21 and it doesn't seem to have taken the correct settings yet, even with a reset. So...if you have a problematic situation with OTA mapping, you may want to revisit your setup to see if any corrections have taken place.
