GOHAWKS, it's my opinion that Dish still needs to negotiate a carriage agreement with the stations in order to carry the digital channels instead of the currently carried analog stations. Then again, it almost sounds like they simply get the digital channels under the terms that they currently get the analogs they're carrying, except they have to down-rez them. I really don't know (yet).....
They do get the digital channels automatically on the same contract as the analog channels once they are turned off. Not all digital channels will be down-rez, just some not all of the ones in HD.
