Just for information, I re-scanned the RTV MUX, after deleting the transponder. The MUX appears to scan in, I get a list of channels, including the service channels 5 & 11, which are reported for TNN. I am not able to get video. My signal shows 74% and my quality shows 0%, but jumps to 92% intermittently for half a second - with the FEC set to either AUTO, 5/6, or 7/8, but not on other FEC settings. I have the AZBOX HD Prem. Plus, 10 ft. mesh dish, and dual C-band LNBF.
