I looked into the Roku a bit more and it does need an HDMI cable, which it doesn't come with. I get the HDMI connections now. Here's my 4th revision which includes a couple more Rokus, HDMI connections, and another switch. Hopefully it's all correct because I just ordered $700 worth of goodies If anyone wants to know what all I had to buy let me know. I opted to go with Rokus instead of TiVo Minis, Amazon Fire TVs, Apple TVs, and Chromecasts, but the connections would basically be the same as far as a MoCA Network itself.
