My first 622 was installed last Thursday, replacing my 721 receiver. I loved it so much, I ran out to the local Dish retailer and purchased a second one not 16 hours later to replace my 522 receiver. Both are hooked up to HDTVs. One is running 720p, the other 1080i. The picture is so damn crisp, I cannot get enough of it. I get annoyed when I cannot find something hi-def to watch. :lol: And the receivers have both been working fantastic so far. I have one in single mode, the other in dual, and though I haven't been driving them hard with recordings and whatnot I have not had a single problem yet. (Now that I've typed that out, I'm doomed.) Going from a 522 to a 622 is almost painless. The interfaces are exactly the same, with the addition of a few more choices hi-def specific. I always did find the 721's menu system almost stupid, but loved the speed it all functioned at, especially the guide. Now the 622 blows it all away. Even I, as A Man, cannot keep up with the speed of the scrolling guide anymore. I have been a Dish subscribed since April of 1997, starting with the 3900 receiver. Remember how sllllllllllllllloooooooowwwwwwwwww that thing was? It took like three seconds just to go from one channel to the next in the guide. :lol: Just to add some balance to this post, I do have a couple of gripes with the 622 to point out: 1. The receiver runs a bit hot. The hard drive seems to function full-time no matter what state the receiver is in. (The 522 was the same way.) 2. Even though the 622 is designed for HDTV, the out-of-the-box HD output setting is 480 (i or p, I forgot which)! What's the deal with that? The installer didn't know that, and if I had not have been smart enough to look around in the menu I would not have caught it right away. I wonder how many people who are not tech-savvy will never know to change this setting? Nice product, Dish.
