Even if the Sathawk worked perfectly, it still wouldn't handle 4:2:2 video. If you want to watch feeds, many of which are 4:2:2, the AZbox is the best bet.
Much has been made of the "problems " of the AZbox, but it has been a great receiver I've gotten it, last April. The AZbox tries to do a lot of things that are not typical receiver things ( all the PVR functions, movies , u-tube, streaming video, etc ) . I doubt that all those "other" functions will ever be perfected, but that's not why I bought the box. It's a fine receiver because it tunes more different formats than any other, at the moment.
