P.S. If something different happens January 1, don't blame me!
Explanation from DirecTV's upper management
If you currently do not have distant network feeds, you will not be able to get them, with or without waivers. If you disconnected them you cannot have them reinstated. Those customers who presently receive their distant network feeds will not lose them (emphasis original), even if you presently have what we call local-into-local channels. We are not going to police the accounts and turn off these channels to customers presently receiving them. In effect, these customers are grandfathered. They receive such channels, particularly those in the upper 300's, because they have either obtained a waiver from their local network affiliate or because they live in an area where they were eligible to receive them. Regardless of the situation, these customers will retain them after January 1st. There is no need to fear you will lose channels to which you are presently subscribed.
I'm just reporting what several upper-level folks told me.
