I'm trying to setup a Mini with my Roamio Pro. I'm new to Tivo and the Roamio is working just fine. Note, here are the instructions from the Tivo website on Mini installation: 1) Connect TiVo Mini to the TV. - For high-definition TV, connect the HDMI cable (included in the package) between TiVo Mini and the TV. - For other TV types, use component and/or composite breakout cables (available in the TiVo Store). 2) Connect TiVo Mini to the home network using Ethernet or MoCA. - Ethernet: Connect TiVo Mini to an open input on the router or to an Ethernet jack in the wall using an Ethernet cable. - MoCA: If you use a MoCA network in your home, connect the coax cable from the wall to the MoCA jack on the back of TiVo Mini. 3) Plug in the TiVo Mini power cord. 4) Make sure you have a direct line of sight between TiVo Mini and your TiVo remote control. If you plan to put TiVo Mini in a cabinet or other enclosed area, you will need a TiVo IR Adapter. I noticed that instruction #2 uses a "or" for the type of connection. I choose to connect my Mini via Ethernet and a RG6 coax connection was NOT made. Well, I was getting the V70 error (Cannot Connect to DVR). I called Tech Support and they stated I needed to connect both Ethernet and RG6 Coax and set my Roamio network setting to "ethernet+MoCA". FYI, my Mini is activated on my account. So is the Tivo Technician correct? If so, they need to change the instructions since when I read the "or", I implied that I could just use the Ethernet connection (and all the data would be sent from the Roamio to the Mini via IP).
