I just followed the instructions in the book, and they worked for me, so I don't know if I can be much help, but let's try.
In the setup menu, I selected "ethernet" (or "networking", whatever the option is called). DHCP and DNS were both turned off. I turned them both on, and then clicked ok or apply (again, not in front of my player, so I can remember the exact words.)
At this point, the unit "froze" for a few seconds (it was obviously going out and getting the appropriate info) and when I went back into the "DHCP" menu option again, I found that all the pertinent info was filled in for me by the player (IP address etc...)
So, first thing I would do it enable those 2 things, then go into the DHCP menu and see if the player was able to get the info automatically.
Also, if it works for your xbox 360, what you could do is, plug it into your xbox, and under the system blade of the xbox dashboard select the network settings, there are network tests you can run.
These tests will check your DHCP and NAT (as well as other things) and may give you clues. I know for myself, my router by default was configured for "strict NAT". As a result, I couldn't go online with some 360 games (I could with Halo2, but not Gears Of War). So I changed some settings and it fixed things.
Also maybe make sure you have PnP (plug and play) enabled on your router? (Not sure if that would help).

I've got cable internet (always on), the modem's connected to a router, then an ethernet cable from the router to the HD DVD player. This is the same ethernet cable that's usually connected to my xbox 360 and works. Not sure what to do....any help is appreciated!!
