I was wondering the same thing. The specs on Denon's site aren't exactly clear. It isn't reassuring how they scrimped on the outputs.
Any player released after November of last year, such as the Denon, is required to be Profile 1.1 or better. If there is no ethernet port, there is no question if you know the release date.
These are 1.1 profile players.
Plus - if you need - as in absolutely require - more than a single HDMI output, look at their higher end model which delivers about every possible output you could imagine.
