Yep, I confirm this. A little annoying, but I rarely use "Done" to get out of a menu.
Last night, though, I thought I noticed another "bug": I'm watching Sereal Life on VH1, when suddenly it starts changing channels, and then shuts off (out to the screen saver). I start freaking out...it turned back on, then went to the guide, back out to the show, a quick channel change, and then off again. I'm thinking, "HOLY sh*t!! THIS THING IS GOING BACK!!" I was getting furious....when suddenly I heard laughing. Out my front window, standing on my porch, is my brother-in-law. Bastard. He brought over his Dish remote for the sole reason of driving me nuts. Mission Accomplished!
BTW, he doesn't have a DishDVR, but his remote worked just fine for basic TV viewing.
