Local PBS channel guide shows different programs depending on Source viewed.
Three sources, CABLE, TVE and Locast.
Local PBS channel has the same Station ID (34197) on all three sources.
Station's website schedule agrees with zap2it which agrees with TVE source.
Cable and Locast agree with each other but show different programs airing.
Performed a Delete and Recreate Guide Database for the three source at the same time.
Still shows different programs.
So far I'm only comparing airings for Wed 3/3 7-10pm since that's where I first noticed the discrepancy.
