I lost the OTA HD signal on my local ABC Station last night. They broadcast the same programs in standard 4:3 on a digital sub channel I was able to get it. This morning the HD channel came back on but I can no longer get on my VIP 622 receivers. I can get it on both of my TV receivers. I have deleted and rescanned several times. I get a signal strength but no picture or sound. I still get the digital sub-channel on my 622s.
