I just purchased a Bolt and a Bridge to create a MoCa network so I can still use my Roamio plus. The TiVo product page for the Bridge says: "Do you have multiple TiVo devices? Want to network them all together seamlessly? Simply connect the TiVo-renewed Bridge to your home’s existing coax wiring or ethernet and create a lightning-fast network. All of your TiVo devices will receive TV signals and a full set of advanced TiVo features through your home network." Will I need a second cable card for the second TiVo? If so, what is the value of the MoCa network?
