I see that 7-2 WHDHDT2, which is 460 on FiOS here in Boston area has the wrong listings, it is showing RTN.
I called channel 7, and they said it was wrong and that 'This TV', an MGM affiliate was starting on 7-2 and on FiOS
on 460 by 'the end of the week'
The FiOS program guide is showing it is RTN, while Tribune/Tivo/etc is showing 'This TV'
Another case where the FiOS guide is WAAAAY off.
Answering my own question.
WJAR-10 from Providence just turned off WeatherPlus and added RTN on 10-2
One 8' quad antenna later, and voila, my tivo is happy and I can watch RTN! in Boston!
