I have an HR20. I used to get my HD locals via antenna. A couple of months ago my HD locals went up on the sat. When that happened my guide changed. I gained an extra substation on all the locals that D* now carries on the sat. This matches reality. Now when the cutover happened Tuesday night, my local Fox and NBC stations switched over. Fox did not change frequency, but NBC did. However I didn't think I would have a problem since my locals were now coming from the sat, right? Wrong. My NBC channel would no longer tune in, I got the the "searching for signal on off-air antenna" message when I tried to tune to it. I rebooted and reran my antenna setup and now my main channnel, 13-1, works, but 13-2 does not, and it did before the cutover. If my locals were being delivered via sat, why did I have an issue, and is there a fix to get my 13-2 back?
