I also have a 722 and it has problems with any OTA signal that is below 74. One of our local stations here in Lansing Michigan just went all digital and moved from 57 UHF to 10 VHF. I bought a uhf/vhf antenna and I still can't get a reliable signal from them, 20 miles from transmitter. I had peaked the antenna to get around 70-72 strength on the 722, but that will not provide a stable picture. I can plug the same antenna directly into my sony KDS-60A3000 tuner and the same signal strength will provide a stable picture. I think it is a combination of lower signal strength and the fact that the 722 tuner is not as good as the one in my HDTV. I guess I will have to put my antenna on the roof after all.
