Hi all...brand "newbie" here, anxious to join the Tivo community, but I'm having problems getting started. I am trying to hook up a Tivo dual tuner model thru my Medicom cable service. I have a RCA DCM-425 cable modem that I'm hooking thru directly to the ethernet connection on the Tivo, and I do not have digital cable, so I do not believe I need a cable card. When I get to the setting up part, it tells me that a DHCP server could not be located on the network. I've tried powering the Tivo down several times, and even called Mediacom last night to ask a tech, and all he could tell me was that I needed to make sure that when I set it up, I allow for a dynamic IP address, and that the DHCP was not ever used by Mediacom. HELP! Does anyone know how I can go about getting going here? Thanks very much for any insight into a question I am sure has been covered many time here...but for us "newbies", it's all fresh!
