The very few stations I have ever observed with mismatched TSIDs threw several television sets for a loop and had to correct the issue by correcting the TVCT TSIDs to match the PAT TSID. This happened several times in Canada with the Global stations, for example. I have seen very, very few stations with mismatched TSIDs, and I've seen TSReader data output for over 2,600 stations.
This is the same setup I run at Marion, Shelby and China Grove. Marion been running this setup for over 3 years without any problems.
With all due respect, your other stations are not running that same setup. Observe:
TSID is 4029 in the PAT and both locations in the TVCT.
TSID is 4043 in the PAT and both locations in the TVCT.
TSID is 4140 in the PAT and both locations in the TVCT.
The only one that is different is Statesville, where your image indicates you are running 1797 as your TSID on the PAT and the 9-9 TVCT (the one in which the PSIP works correctly) and 1839 on the 64-9 TVCT (the one in which some TV sets are ignoring the PSIP).
EDIT: Even if that's not the problem, it still does not follow the PSIP implementation guidelines in ATSC A/69. Section 6.3.1 (page 28) states, "The channel_TSIDs listed in the VCT are required to match the TSID listed in the MPEG Program Association Table (PAT) where the digital service is transmitted." A strict interpretation of the guidelines would suggest that a TSID mismatch like WSOC-ST has should not map 64-9 to the second stream on RF46 and should instead map to the second stream on whichever RF channel has the PAT TSID set as 1839.
