Well, in place of the HD feed of KOCO-DT, DirecTV is currently broadcasting a splash screen that reads:
"No need to call us. We are aware this station is temporarily unavailable, etc."
The SD feed of KOCO is being broadcast just fine. I'm glad I saw the message on KOCO.com and switched my recording of "Scrubs" tonight from the HD to SD channel!
Anyway, I suspect that KOCO is attempting insert their "school closings" / "winter weather warning" graphics into both the HD and SD feeds, and they've somehow scrambled the HD feed for both DirecTV and Dish Network. Just my theory, but the timing of the alleged "equipment problems" for *both* DirecTV *and* Dish Network _at the same time_, is awfully suspicious.
*Update*
Koco.com has changed their story:

They are now claiming that the ice storm interrupted their HD feed, and that they are working with both providers (DirecTV and Dish Network) to re-establish the signal.
