This TV started up on schedule this morning. 10.2 cut over from Weather Plus to This TV at 10:00. About 10-15 minutes later the new subchannel 10.3 appeared with Weather Plus.
WIS has the following announcement on their Web site:

The online program guide seems to be screwed up, hopefully only temporarily. The first movie (which is playing as I write this) is "Disaster on the Coastliner" which started at 10:00 by the looks of it. When I went to
http://columbia.thistv.com as directed by the WIS announcement, on the home page I saw "On Now: 9:00am - 11:00am Disaster on the Coastliner". But under the "Schedule" tab it listed this movie as starting as 12:30pm.

However, the OTA PSIP guide data is in place and correct (as of right now), so if you have a converter box or tuner that displays a PSIP guide, you're in luck. (Up in Spartanburg, WSPA has had Retro TV on 7.2 for several months but still doesn't have PSIP guide data in place.)
