I've had tivo 12 years and love the moca. Done a lot of experience with them and have the following Tivo Roamio Plus Tivo Mini x2 Tivo Premier x3 Tivo Series 3 HD Tivo Series 2 with PLS
FYI, You can also use some old DirecTV Deca units, which are the same as moca except they run on the opposite freqs (so don't mix them with your raw cable signals!) and they're way cheaper than moca adapters. Just run the raw cable signal to the roamio and an Ethernet line, then split the rest of your house off from the raw cable and use a deca unit with power inserter to inject another ethernet signal throughout your home's coax. At each coax location in each room, just add another deca with power inserter and split the Ethernet signal back out and use it as you would any other Ethernet signal (directly into a component, into a switch, etc). Use this for each mini you want to install. Basically same as moca, only cheaper!
Something like this:
DIRECTV Broadband DECA Ethernet to Coax Adapter (DCA2SR0 ) Generation II
I use the old gen 1 white ones with no issues, and these are newer gen 2's.
