Advertisements I'm having a problem in which my Living Room Tivo (Humax DVD) "sees" my other 2 Tivos (SA in office & Humax DVD in BR), however, the SA in the office and the BR Humax do not see the LR one. All of this occured after I replaced my cable modem. No other changes were made - same router and switch extension. Since I only changed the modem I wouldn't think that would affect the Tivos from seeing one another. Anybody got any clues? Thanks in advance.
