Very cool. I'm mostly running YTTV from my CCwGTV, which makes it all wireless, and have been able to get top notch streaming quality. However, I also have EoC for wired backhaul on a mesh network.
In my case, i don't have cable TV (assuming you don't either, if you have YTTV) and therefore don't need the split Ethernet/cable capabilities that MoCA offers. So, i use a G.hn powerline EoC kit and it works perfectly to pass Internet over the RG6 in my house. I'm using these comtrend units and have had no problems whatsoever. I've only got a 400Mbps connection from my provider but can still get speeds over 330mbps with some mid-grade Asus Wifi6 meshes routers multiple rooms and brick walls away from my modem. :)
Did you go with MoCA because you're running cable in the house as well?
