I realize that this is a month after the last post, but I read through every post so I feel like posting. Lol
Chromecast streaming over WiFi is just a compressed internet signal. It's much easier for this medium. And the Chromecast is buffering the signal so you don't see any small glitches. As for Hulu... Hulu's signal sucks. Quality is horrible. Try the new Vudu streaming on Chromecast. Vudu streams in 1080p, but the only way they get it to work as well as it does is they use Peer to Peer. Much more efficient of a delivery system. Watch Netflix 1080 and you'll get buffering.
As for Moca the throughput is much less, but the convenience is there. It's not the same as an IP signal. But it is very reliable for the short distances you have in your home. And MOST homes should be plug and play.
There are some exceptions and people should be cognizant of them. If your house is relatively new or your electrician (or whoever wired your coax) was good, all your Coax wiring is wired to ONE location. At this location is a splitter. It takes the signal coming in to the house from Comcast or Fios or Cox or TW or whoever and sends it to your TVs. If your house has a weak signal coming in or you have more than 4 connections a signal booster was probably installed.
A booster or amp may harm your Moca signal if it tries to get through. It's most important to have the booster/amp before the splitter and not in-line with any particular signal. (Also, these boosters can effect your internet signal so it's recommended to use a splitter before your booster to send an untouched cable signal to your modem.)
There are approved Moca Amplifiers available if it's needed.
Another thing is the Splitters you are using. Most splitters provided by the cable companies now are fine. But it's important to use splitters that are rated above 1ghz as a Moca Signal is in the 500mhz - 1650mhz. Plus they must be 2way splitters. There are also Moca Splitters with POE Filters built in.
Also a bad fitting could affect a Moca signal but maybe not a TV signal. Look inside the end of the Coax Cable. Are there any pieces of metal touching the copper center conductor? If so either replace the fitting (tools available at most hardware stores) or if you can just use tweezers and pull it out. Also, it sounds stupid, but some fittings just plain won't work well.
Another important thing to know is that you can't have TWO Moca networks on the same lines. So if you have FIOS you all ready have a Moca network and you do not need to setup a Moca network for your Tivos. This means NO Tivo Equipment should need an Ethernet or Wireless connection to the network. Just the Coax. Comcast, Cox, and TW (among others) have all started using Moca networks for their Multi-room DVR services. So check with your service to see if there is all ready a Moca Network in place. --> What's great is you can grab a Moca adapter and throw it on a coax and pull internet off it for a hardwire connection anywhere there is a Coax cable.

Explains it all very well.
I hope this is all helpful to anyone still linked with this Thread and anyone else having problems. Hope it's understandable. If anything I said isn't true feel free to correct me. Though a source for your different information would be nice.
