These channels are available TEMPRALILY on the 5700 channel block. Dish is in the process of REMOVING all channels from 121° since they are discontinuing the SuperDish.
The channels are available at 118.75°.
The easiest way to get these channels back and more is to call the number on the channel slate and set up a dish upgrade. All you have to do is have the dish replace with a slightly smaller dish that points to 110°, 119° and 118.75° to get just about all the programming out there. It's called a Dish 500 Plus
See ya
