Josh,
I'm not at home and don't have the Denon 2900 with me, but over the weekend I was waiting for it to load a DVD and thought, "Man, this is taking some time." The next time I'm home I'll give it a look see, but at this point my recollection is that it takes some time. I just popped a CD in my Pioneer DV-45A, and it seemed to load up and get playing much faster than I remember the 2900. The tray on the 2900 is also very deliberate, i.e., slow, especially compared to the Pioneer. But since that is the only area where I think the Pioneer wins, I'm still more than happy with the Denon. You, however, may find it drives you crazy.
I'll try to get a better gauge on it the next time I'm home, and I'll report back here.
