Dish Network has launched a new DVR, the ViP722. It is an improvement over the ViP622 in that it has a 500GB drive, giving up to 55 hours of HD content compared to 30 for the 622, and it is black, and… well, that seems to be it. Pretty much the 722 is a black 622 with a larger drive. Like the 622 the 722 has two satellite tuners and one ATSC tuner, and it can output two programs simultaneously – one HD and one SD.
If you already have the 622 there is no reason to upgrade since you can use the latest update to enable USB 2.0 storage to expand your capacity.
