Unless Denon has greatly improved this model from last year's, which I own, I would look elsewhere. The video performance of my DVD-555 (the silver version of the DVD-1710) is good, but it has the slowest transport response I have ever experienced and is not acceptable. It literally takes 2-3 seconds from when you press a menu option to when you actually get to that part of the disc menu. (BTW - I only own the DVD-555 because it was given away with my Denon receiver.)
I think the Sony DVP-NS75H, Oppo OPDV971H, or Panasonic S77 would be better alternatives.
