I have an XL4 in the living room and am getting a new Premiere to replace the Series 3 in the bedroom. There is no internet cabling in the bedroom so I'm planning to use Moca to enable the connection. I live in a 6-unit apartment building and all the coax cable drops from two 8-way splitters on the roof. In other words, each Tivo is connected by a discreet coax cable, possibly from two different splitters. Will Moca work in this situation? And if so, just out of curiousity, how?
