Cox Cable in Fredericksburg VA has a fairly standard lineup, including WTVR (CBS) from Richmond. But the strange part is, they only carry WTVR during newscasts, any other time it's replaced by a slide that says WTVR is only available during certain hours.
I live in Spotsylvania County and we have FIOS here at home, I get WTVR and WRLH (FOX Richmond) with full access, not just during newscasts.
I've seen that happen elsewhere. I know in Scottsbluff, Nebraska when they got their own NBC a couple years ago cable kept KUSA Denver but for newscasts only.
