MUST I upgrade to SWM/DECA hardware for Whole Home DVR?

    Prior to upgrading to D* HD-DVR three years ago I enjoyed multi-room capabilities with the ReplayTV 5000 units I had in my home. These had been connected to my home hard-wired ethernet network which the ReplayTV units used to communicate to one another for playback or sending programming commands from one to another.

    I lost the multi-room capability when I upgraded to D* HD-DVR and am now considering going to a D* Whole Home DVR configuration. Everything I have read so far implies that I now have to run another ethernet network within my home, although it would use the coax already in place for DirecTV. I think I understand what would change (upgrade one receiver to HD capable, install SWM, DECAs, PI, etc.) but why?

    MUST I install all of this additional hardware to establish an ethernet network which the D* receivers can use when I already have an existing hardwired ethernet network already in place?

    Are there advantages to having the SWM network separate from my regular home network? One can think of is separating the D* traffic from my computer network, but are there others?

    Thanks all!

    See this thread for information about using your existing ethernet network for whole-home DVR.

    Thanks Bob. I had scanned through that thread prior to my posting but with so many responses there it was difficult to determine the answers to my questions.

    If I've read between the lines correctly, it seems that it is possible to use an existing ethernet network BUT it depends a lot on how you communicate with D* and it's currently an unsupported configuration. Is that right?

    Must - no.

    Should - probably.

    If you want it to work properly and flawlessly with support from Directv I would let them install the DECA/SWM WHDVR Service and be done with it as I just love mine and I had it connected via my LAN but it didn't work flawlessly and gave me periodic problems.

    Hook up your receivers to your home network. Follow the instructions in the other thread about sending an e-mail to DirecTV. They will turn on MRV in an unsupported mode for you. That's it.

    It (ethernet) is unsupported, and it will stay that way. You can get it turned on in unsupported mode, just follow the instructions to do so. You can't get any help with making it work or fixing problems from D*. (you have to come here for that):)

    As yet another person who was running it unsupported (and worked for many months with the group of people who were testing it), I can say that as well as the unsupported approach worked (it still costs you the same $3.00 per month), the DECA approach works better for me. Fewer glitches and smoother trick play, is how I would characterize it.

    In my situation, I'm running both. I have two DVRs and one HD receiver on SWM and DECA. I have a 3rd DVR on a different dish, and it is integrated with the WHDVR system with a wireless gaming adapter. As such, there is no support for the 2nd dish (w/r to WHDVR), but at least if I choose to, I can view programming on it and from it. It doesn't work as well as the SWM/DECA setup, and I don't use it much that way. I have it setup so I can use it for WHDVR if I choose, but mostly because it was an interesting technical challenge.

    I would strongly recommend going SWM/DECA. You get a better sat signal (as a side benefit), and WHDVR works somewhat better.

    If you have a well architected wired LAN with 'current' equipment (switches/router/etc.) then while the configuration is officially unsupported by D it should work just fine. I have 2 HD DVR's and 2 HD rcvr's that have all been running MRV flawlessly on my existing network since MRV was first made available.

    I agree a DECA/SWM configuration will provide better overall service. However I also agree a good home network can support satisfactory MRV for most people, most of the time.

    I actually have a hybrid system. I've got 3 DVRs and two receivers on SWM/DECA, plus another DVR not on that system. The DECA cloud is connected to my LAN, as is the fourth DVR, and all play together.

    Thanks for all of the info and feedback here! I do have a very stable home network, and as I mentioned in my original post I was regularly using it for my ReplayTV DVRs to communicate to each other as well as stream content back and forth.

    At the very least I will integrate a SWM8 unit with HR-24 and try MRV over my existing network after turning on the service with D*. To me, the added complexity and components for D's DECA network is a concern, adding multiple new potential points of failure. I may end up going to that configuration, but I'm going to test with my existing network infrastructure first.

    Thanks!

    I've been using it for about 18 months and it/they aren't/haven't been a "concern".
    Actually I might have had more problems using ethernet. :lol:

    If your current wired network is stable and you were using it to distribute video before then you should have no trouble using it for MRV. While theoretically SWM/DECA may at some point in the future allow you to do something that you can't currently do over a well architected wired network, I have yet to see any indication of that capability being rolled out anytime soon.

    Keep in mind your replay equipment was streaming SD, not HD. Big difference in bandwidth.

    Yes, HD is about 6 to 7 times larger than SD.

    Bandwidth ratio is about 5 to 1 for HD to SD.

    Well, I had heard 6.5 to 1 but maybe that was MPEG-2 and not MPEG-4!!! :D

    As long as he has a well architected wired LAN it will be able to EASILY handle HD. A 100 Mbps wired LAN has plenty of bandwidth. My wiring is all CAT 5e and all my switches and my router support 1000 Mbps. Note that the Ethernet ports on the D equipment is currently only 100 Mbps.

    Again, any technical benefit of SWM/DECA, outside of the benefits of ease of installation and ease of support, which are benefits for D and their installers not directly benefits for the consumer, are currently only "specification" benefits and are not being utilized by anything D is currently doing or has even announced intention of doing.

    It was actually interesting if you watched the most recent D investor briefing, their chief technologist admitted that one of the reasons they went with running the network traffic over the coax lines (made possible by DECA) was that the installers understood how to work with coax.

    Not sure where you got this, but it isn't correct.
    MPEG-4 HD normally "averages" around 9 Mb/s, but can be 16 Mb/s and trickplay can be over 30 Mb/s, so the receiver IS USING 100 Mb/s ports.
    "All you need to do is" use DirecTV2PC and monitor your network to see these.

    Sorry about that...my fault for trying to do many things at once this afternoon. That should have been 100 Mbps and 1000 Mbps (Gigabit Ethernet). Sorry if I confused anybody.

    If your having them upgrade equipment anyway, just go deca now.. It'd be more expensive latter i have a feeling.. And there is ZERO reason not to go deca... There are POSSIBLE downsides to not going deca... Thats as simple as I can put it...
