Just got mine today, left Directv and an HR34/Genie.
Menus are taking awhile to get used to, but they've improved a lot of things over the 722 when I had it, and I love the look of GUI. Its also super fast moving around.
Why did you leave the Genie? I have a Dish 622 and am looking at all options and DirecTV is putting some enticing incentives to jump and 5 independent tuners is very appealing. Dish on the other hand after 11 years wants to change me $50 for a Hopper and jack up my rates.
