    I use my XL4 as a bridge for all of the devices in my entertainment center by connecting a switch to it's Ethernet port. I have 3 game systems, two additional TiVos, my Smart TV, my Ooma and a wifi access point connected to a switch, which then connects to the XL4s Ethernet port, which then bridges over MoCa to my office where I have a MoCa adapter connected to another switch which then connects to my router.

    If your Mini is right there next to a free ethernet port then you might as well use that if it's not needed for anything else.

    Great! Thanks for the suggestions. Hopefully this brings up the PHY value.

    Took the Actiontec adapter out of the equation and everything work likes a charm now. Now to just hook the Stream straight back to the router and everything will be good to go. It would have been nice for the Mini to act as a Moca Bridge as well so you could use the Mini and Stream in conjunction with each other (just a thought). Now what to do with this now useless Actiontec adapter? Thanks again for the help.

    That sucks for those stuck on cable cos using SDV. That may require an extra amp higher up, as now each TV needs another -3.5dB split on it...

    Luckily, if Comcast ever implements it, many systems will not need TA's for TiVo, only for MCE, since they already have support for it over software for XoD. Highly unlikely they would use that awful technology, however.

    Anything good should work with MoCA, or you could put one amp on the whole system and then a POE filter and then splitters. However, my parents have an old RadioShack POS amp and it works fine with Comcast's version of MoCA on a DCX3400.

    Here's the setup I used at my parents house with an amplifier and MoCA - it took a little time to figure out how to get it all working but it works. The TiVo connects to the internet through MoCA - will be adding a Mini or two in about a month (already have them!).

    I used Broadband Extreme 1 GHz rated splitters, and the amp is a Motorola BDA-S1 (I am going to switch it to a BDA-K1 when I install the Minis such that I can amplify the upstream as well, the S1 only amplifies the downstream, the K1 does upstream and downstream). The diplexers in use were Holland STVC.

    The diplexers were used to separate the CATV signal from the MoCA signals, as the amp is only rated 5 - 1002 MHz and amplifies the CATV signals. The diplexer sends the higher frequency MoCA signals around the amplifier and then the second diplexer re-combines the signals onto a single cable.

    I also would've put another MoCA filter between the MoCA Adapter and the Cable Modem, but the Cable Modem is a Motoroal SB6121 which has a built-in MoCA Filter.

    Further, they are on Charter and use SDV. I used a 2-Way splitter at the TiVo with one leg going to the TA and the other to the TiVo. I also put a terminator on the TA's output.

    If I recall correctly I was seeing about 230Mbps on the TiVo for the MoCA speeds - I don't recall what the signal strength of the CATV is, but the incoming service was +3dB and the modem was sitting at -4dB (its about 100 feet of cable away). The CATV run to the TiVo is approximately 150 feet (so a -6dB drop). I am guessing the signal level of the TiVo is about -5 to -10dB. I plan to hook-up a cable modem the next time I'm there w/ the Minis to get a value.

    Feel free to ask me any questions on the setup.

    I have wired Ethernet (1 Gbps) pretty much everywhere in my house.

    Is there any reason/advantage to using MoCA instead of Ethernet for connecting XL4 to mini?

    No. 1GBPS Ethernet is probably faster.

    MoCA is fine when you can't/don't want to run new lines everywhere in the house.

    I have 1Gbps everywhere and still opted for MoCA for my new Minis. Using MoCA allowed me to retire ethernet switches at those locations that are no longer needed.... so I save a few extra watts by using MoCA although perhaps I lose that back on the TiVo XL4 as it might consume a few more watts when the MoCA bridge is in use.

    I have a question related to security. I went ahead and set my two Minis up with MoCA and they are working well. I have not yet ordered or installed a POE filter for my coax network.

    What are the security implications if I don't do this? Would any neighbor device on the same Comcast physical network be able to get an IP address from my host TiVo with the MoCA bridge?

    At the point of entry into the home I have a ceramic fuse surge protector installed inline on the coax network as I'm always leery of coax power surges taking a lot of expensive gear out (and we get some serious lightning storms in Colorado). It will be a bit of a PITA for me to install a POE filter inline next to that surge unit.

    Looks like I'm going to have to use MOCA. My Mini won't connect to my Cisco gigabyte switch. It does connect to my 100baseT switch, though. Has anybody else had a similar issue?

    Presumably you have a splitter at some point downstream from the surge unit that branches your coax off to the various rooms? Install the POE filter on the input side of that splitter.

    I tried using MoCA for a while with my Elites, Premiere, and a few other devices. While transferring between a couple of TiVos it was fine. But when I had multiple transfers going concurrently, like to TiVo Desktop, the transfer speeds took a hit. So I went back to my gigabit backbone.

    For me, any Minis I use will be at a location that already has a bunch of networked devices. So I can't get rid of any switches anyway. So there is no advantage for me to go to MoCA. If I had a location where the Mini would be the only network connected device I would use MoCA for it instead of a GigE switch.

    I don't have a traditional splitter per-se. I have a coaxial multiport panel, which has very tight connection tolerances, I'm not sure if I can get the POE filter to fit.

    The key thing is, "do I need it". What's the real-world risk of not installing it?

    I see. I'm no expert on network security, so I can't really speak to that, but I think there's some risk that MoCA signal leakage outside of your home somehow causes problems for your neighbors, and the cable co. traces the source of the problem back to your cable plant. Their fix, of course, would likely be to install a POE filter at some point (maybe further upstream from your panel if it won't fit in there).

    OK, thanks. I will check and see if I can find a point of entry filter locally and if so I will see if installation is possible. I don't want to degrade my neighbors service.

    Good luck finding one locally. I don't think anyone carries them (or even knows what they are) in my neck of the woods. But your cable co. might just give you one if you ask - chances are they are using them in their own whole home DVR installs and may be happy to give you one if they understand it could prevent problems for them.

    I just ordered one from an eBay seller for about $8 shipped IIRC.

    Worked like a champ! All I had to do was enable MoCA on the XL4. Just can't believe it worked that easily. Very impressive!

    BTW, I ordered by mini Tuesday morning around 11:00am EDT. There was a $38 charge for 2-day shipping. I just took the free UPS ground shipping. It arrived today! Maybe I'm just lucky it got here in 2 days, but I'm really glad I didn't spend the extra bucks.

    Thanks again Dan for the help.

    Glad it all worked out for you.

    I've paid the extra $3.99 to have an item overnighted to me from Amazon only to have them ship it via UPS ground because it came from the Amazon warehouse the next town over. Always p*sses me off. :) But you can never tell where exactly it's going to ship from so if you need it right away you have to pay.
