Networking Tivo With Mac Os X.3.9 And Voip


I have two TiVo boxes. One is stand alone and one is a dual receiver Samsung DirecTV Box. I have installed and updated both so that they download new program information via land phone line. (Both are Series 2 Boxes.)

But now I'm ready to network them to my Mac work station (Dual 1.42 GHz running OS X.9.3) as well as be able to update programming via internet. My question is, do I still need my old Land Line provider: BellSouth? Can I set up my TiVOs to update automatically off the network using either internet or the VOIP line? Or do I have to keep my land line to allow TiVo to dial up and download new programming info?

Any experience shared on this set-up would be greatly appreciated.
