So I dont' know what happened but luckily I had another diplexer so I tried that (to narrow down things) and directly connected the TIVO and the picture came through. I disconnected it and connected a 1 x 2 splitter to the TV out on the diplexer and connected the TIVO and cable modem and SUCCESS! It may be the flashing light (not full speed) but that's what I had before and I have the MOCA working again.
I'm curious as to the benefit of the diplexer on the 'child' MOCA boxes: if my HDTiVo, PS3, wii and WD Live all work fine through it (a 1 x 2 splitter) why would one need a diplexer there?
Since I don't have 100GB network at all my switches/etc I can't stream blu-ray files from upstairs to down but I can stream DVDs fine.
Thank you again for your feedback/input!
PS Huge Star Wars OT fan (hate the remakes and prequels). Always one of my favorite lines from the movie. I have no name for my Man Cave/theater room. It's eclectic and an old video is on youtube (my videos are by 'wryker'). I need to take a new vid to show the screen and projector and new 'stuff' added to the room. Suffice to say my Star Trek figures from when I was a kid are on display as well as Star Trek TOS figures etc..
The principal benefit of using a diplexer rather than a simple splitter is that there is far less loss of signal level to each device. Instead of giving half (actually less) of everything to each branch, it gives each branch most of the signal in the frequency band that branch actually uses. That was what xnappo's 12:44pm post put numbers on: a level loss of -1db to each branch (-3db is half strength). That means -1db to the MOCA box, and -4db to each of the outputs of the secondary splitter feeding the cable modem and Tivo.
If you used a pair of normal splitters hooked up exactly the same way, with the MOCA box on the open jack on the first splitter, the numbers would be -3.5db to the MOCA box, -7db (these are actually exponents, so -6db is half of -3db: one-quarter strength) to the cable modem, and -7db to the Tivo.
I'm put in mind of the story of how Solomon got his reputation for brilliance: by proposing to act as a 1x2 splitter to divide the baby between the two women claiming to be its mother, he found out who was the real mother (the one who cried "Let her have the baby, so it can live!"), enabling him to diplex instead, giving the whole baby to the real mother.
PS I gave out candy to the trick-or-treaters last night in my customary Spock costume: blue (licensed) original series shirt, black pants and shoes, and unlicensed pointy ears from a costume shop. One girl about 10 years old breathed "Spock!" when she saw me, others asked if I was someone from Star Trek (or Star Wars). One couple ushering their kids around were split between the two - I pointed out, as Spock, that the principle of Infinite Diversity in Infinite Combinations meant it was unnecessary to choose between the two series - and then said, "May the midichlorians be with you." (I hope you don't mind the first prequel reference - the farce is strong in this one.
I keep my sideburns trimmed diagonally year-round anyway.
Didn't have time to work on the eyebrows this year.
