I got my 922 shortly after moving to Northern Cincinnati. We hadn't moved yet and Dish came out to install the dish a week before moving in.
The box was buggy as hell during the install.... I let it set for an entire week running without touching it and when we moved in the following week the box has been generally stable.
There are some issues with the box that I am ok with. However, I think it's a ripoff that they charge $200 for a box with so many issues after owning one for about 5 months now. Dish needs to get the sling issues fixed as well as the EHD recording problems.
This box is more stable than than a 921.... I would compare it to the old 721. The 721 had a ton of "features" that were either removed or simply never enabled but was overall a decent box.
I hope you enjoy the 922. It really isn't a bad box. Dish WAY overhyped it and therefore it will always have a bad reputation due to the fact they never got all the promised features into the box. For $200 you get the equivalent to a gimped 722k with a 1 TB hard drive, and a new guide interface. However it's missing several of the 722's features and also missing a decent TV2 output (Sling issues). The flagship box from Dish is still the 722k IMHO.
