You mentioned a $200 price difference, but forgot to add that the Denon doesn't come with the microphone to do auto setup (but for some reason the model below it does). Add another $65, at least, to your $200.
I went thru the same struggle that you went thru and went with the Yamaha because everything I read said that it was better w/ TV (HD of course), movies etc. I spend more time watching movies than I do listening to CD's or SACD's. Also, the $200 price difference didn't factor into my decision making at all. I figured that I will be using this receiver for years so that difference means a small percentage of pennies for each day or, for that matter, each use.
I am extremely happy with my Yamaha 2500.
