I have a Samsung Blue Ray player that is now hooked up to my FIOS Internet through the wireless router. I have a DVR, but I don't see why you would need more than an HD box. You won't need the IP address, just the name of your router (which it should dtect automatically) and your WEP encryption code. They should have included your WEP code on a shortcut on the PC when they installed FIOS, but if you can't find it you can also copy it from the back of the router. Good luck!

P.S. I have surfed Youtube, and have established the free trials for Blockbuster and Netflix. I like the Pandora music option as well.
