I currently have Comcast basic service with NO Comcast boxes. I use tuners on my Macs to record and then stream to Apple TVs on our two HD TVs. Well, Comcast is going to very soon encrypt basic channels, so I have to do something. I really don't want to go satellite, and we are in a very difficult area for antenna, so I thought TiVo would be the easiest solution. I started reading all about it, and soon discovered that I needed to learn about Moca. Yikes. Looks simple, but the diagrams on the TiVo web site all show a cable modem in the mix, which I don't have, so I'm confused. My setup would be: Roamio Plus at the main TV, no ethernet available Mini at second TV, also no ethernet available Moca adapter in the equipment closet The closet has Uverse modem, Apple Airport Extreme, and ethernet switch What do I need to connect the Moca adapter to to establish the Moca network? I assume router and switch, but will that be sufficient? Thanks.
