Anyone in Columbus, Ohio having a problem getting video for NBC4 HD from Directv, NOT antenna? Last night right before Saturday Night Live, I lost the video for NBC4 HD from Directv, but still had audio. I had to switch to my antenna to see it. Also, the non-HD channel of NBC4 from Directv is fine. Anyone having the same problem? Any trouble shooting I could do? Every other channel appears to be fine. Very odd.
