I had a similar problem with the Memphis locals OTA. When the "big switch" was supposed to happen I got home and noticed that all of the OTA channels had an "off the air" banner attached. I did the OTA antenna resetup and now I have nothing for any of the OTA channels....
Don't know exactly what your issues are, but see sore_bluto post #144 above. If you can articulate exactly what your issue is, maybe we can help. We had an issue here in New Orleans that took 2 months to get fixed.
