I'm pretty sure my install was a mistake; Dish officially doesn't want to install 1000.4 dishes for existing customers yet --- only for new subs, who get new receivers with the new smart card in them.
I just got "lucky" when I got on a chat and got a CSR who happily scheduled an installer to migrate me. The installer didn't realize dish was migrating existing customers to eastern arc (because they aren't supposed to). When the 72.7 channels didn't work (I get a blank screen on all of them), he didn't know why, the tech at Dish he called didn't know why, and the "boss" at the installer's company didn't know why. ALL of them insisted, though, that it wasn't the smart card.
Later that night, I got on a chat with a Dish tech rep who, after about 30 minutes, figured out that I need a new smart card. Nothing to be done until the new card arrives, which apparently can't be accelerated. That tech said, "This is why you weren't supposed to get an eastern arc dish."
I've only lost one channel that I watch (comedy central) often, so I can live with it if the new card somes "soon."
