FOX usually wants to keep subs off the Fox station if possible (bandwidth issues). Thats why until KMSP/WFTC here in Minneapolis did their switch around (putting both FOX & MY in HD on RF29) most of the subs when added went to WFTC My29.
Thanks, gotcha
I need to add something to it. This only happens when the FOX is O&O and also owns the My affiliate in the market. Minneapolis is a unique situation as FOX was on VHF and My is on UHF so folks with indoor antennas have had issues. Thats why they put both FOX & MY in HD on RF29 (FOX is also still on RF9 too)
Look at DFW. FOX has nothing on it (FOX doesnt want to mess with bandwidth for the Cowboys) so KDFI has My, Movies, Buzzr and H&I
