    9 DVRs with both tuners active could be run off 1 SWiM-16 & 1 dish.
    8 in the SWiM mode and the ninth connected to the legacy ports with full function.
    The 8 could used DECA and be bridged to your ethernet [with another DECA].
    The ninth would be ethernet connected.
    You could still add another DVR since there are another two legacy ports on the SWiM-16.
    When you finally exceed 10 DVRs, you next step would be to add another SWiM-16 which can cascade off the first [by using the four legacy ports].
    These two SWiM-16s could have their DECA clouds combined into one, as long as the total DECA count doesn't exceed 16, so that means 15 DVRs + one DECA to ethernet.

    Well, I'm gonna assume that I can stick ten on the Ethernet setup. It's working as it should with nine, so ten shouldn't be a problem.

    I wonder if there really is an actual limit to how many you can have hooked up to your network, regardless of how you hook it up, but rather how many can be streaming from one place to another before you have bandwidth issues, and how creative you get in wiring it all together...

    So far I have the nine 20-700s on four TVs and no problem. Tomorrow, I'll get a 50' Ethernet wire so I can hook up the wife's 21-700. That will make ten HRs on five TVs. If I use MRV, I'm assuming that she can do the same thing at the same time. With different HRs, of course. And I now realize that I have way to many HRs. :lol:

    That's a really interesting question about the bandwidth issues. I can try and see if there's a point where problems occur. Might as well use all five TVs and have them tuned to five HRs that are on my network. I guess that that's the limit I can test at. If you have any thoughts on how else to do it, tell me and I'll try to do it tomorrow. If five won't work, I'll knock it down to four and so on. Any other thoughts?

    just rotate the mrv playback.. hr#1>hr#2, hr#2>hr#3...
    also maybe hr#1>hr#2, hr#2>HR#1....

    Finally got around to adding the tenth HR to my Ethernet network and began to experience problems. A couple HRs dropped off the net. And I couldn't access a couple others. Took a seldom used HR off the net and as soon as I was back to nine HRs, the problems went away. So, at least for me and my setup, nine HRs is the limit.

    Still haven't had a chance to check the HRs ability to run multiple shows on multiple HRs and TVs and see what limitations exist there. I keep starting it and...well, I'm just lazy and it seems like a lot of work and I end up watching something, and nothing gets done. :lol:

    I'll get around to doing it one of these days.

    So if I connected 2 swm-16's via deca to the same network would I be able to handle 10 DVR's with both Tuners (20 Channels)?

    We believe so, but I don't think anyone has been able to verify it yet.

    I can tell you from my testing that a "typical" 1080i program streamed from one DVR to the next shows around 8 megabits /sec. I've gone as far as steaming two programs off a single DVR while steaming one in to it (3 streams total) and showed peek rates around 24 megabits /sec on that switch port (16 out and 8 in). As far as bandwidth is concerned I don't think you'll see any issues. What the limit of the DVR is for encoding/decoding packets is the question.

    I find this a bit hard to believe since "one DVR" is limited to one incoming & one outgoing stream [two total].

    i can tell you that i have a SWM LNB cloud and a SWM8 multiswitch cloud....two differnt networks talking to one another.


    hr24 - h23 - d12 on swm lnb - deca cloud

    hr23 - hr22 - hr22 on swm8 switch - hard wired via ethernet

    all hx's see and share with one antoher

    Hm. I'm going to have to go back through my notes. I swear it was 2 out and 1 in on a single dvr using direct2pc as one of them. I could be wrong, that was a while back.

    Any reason you didn't dump the 2 dish solution for a dual SWM8 approach, or are you just waiting on a SWM16?

    If you have more than one DVR, it can be easy to get them mixed up.
    In the early days it was one stream in or out and couldn't do one each way, but that has been resolved so it's one in and one out now.
    If you use DirecTV2PC, it doesn't change the total count, so the DVR will feed either it or another client, while the DVR can still MRV from another DVR [staying within the one in & one out limit].
    If you've started streaming to one client, another client will see a red circle with a white - in the center, in the playlist, to show the DVR's recording aren't available at the time.

    NO reason, just wanted to play with it and see how well the system works, its limitations and such. so far so good...no issues.

    Two nights ago, the wife and I settled down to watch TV. First time that day I'd had an HR on. I was using one of my 20-700s with a WD EADS 2TB internal and the picture was very jittery. Every program that I tried was jittery, whether it was recorded on that HR or one of the other ones.

    OK. Figured there was something wrong with either the 20-700 or, worse case scenario, the WD HDD. So I switch to another 20-700 with a Seagate 1.5TB internal and the same thing happens. Now I'm getting worried. Off to the master bedroom, where the 20-700 with a Seagate 1.5 is. Same thing. But, now I've tried both dishes and gotten the same results.

    Back to the HR I started off with. Unwatchable, but no problems with live programming. Thoroughly puzzled, I sat back and thought. The only common thing the two dishes have is the MRV. I shut the MRV down on that HR and the picture on a recording is still jumpy, but not as bad. Watched a couple hours of shows and it seemed to get better.

    Figured it was because D* was gonna do the switch from beta to a permanent MRV and gave it no further thought. Yesterday, I considered the Ethernet system that I had installed myself and wondered what would happen if I started isolating HRs. Ended up taking them all off the MRV beta mode. All the HRs cleared up. Began adding the MRV to each HR and the jittering began on the recorded shows again.

    Gave up and took all the HRs off MRV. Now they are all playing properly. Must be the Ethernet system. I was totally convinced that I had screwed something up. But then I thought that the problem had just popped up and I have been running nine HRs on the Ethernet system without any problems. More confusion.

    Then, I go downstairs and turn on my computer. Can't access the Internet. My firewall is shut down and won't come back on. Reboot the cable modem and the router and the computer. All come back up and look OK. Computer still can't get the Internet. Reboot modem again. This time, after all the proper lights come on, the modem goes into standby. Reboot the modem four more times and the same thing happens.

    Now I'm running out of patience and call Cablevision. They tell me to go get a new modem. I take the old modem and get ready to go to the CV store. Front door lock won't work. Have to use the deadbolt lock.

    Finally, I get home, hook up the modem and call CV to authorize it. Internet comes up and when I go to the HRs they are fine. Turn on MRV for all nine and all is well. All that trouble and just a bad modem, which is pretty common for CV. At least I'll know what to do the next time the picture gets jittery.

    But, what I don't get is how the doorknob got screwed up. Coincidence or convergence? Or just my bad luck? :)

    The SWiM-16 First Look says that the DECA cloud is limited to 16 nodes. So in your scenario, only nine nodes are being used. If you have a ninth and tenth DVR coming off of the legacy ports, could you send a third cable (off the SWiM splitter) to the ninth and tenth DVRs and use DECAs with PIs to connect them to the cloud?

    Or if you connected a multiswitch (6x8) to the 4 legacy ports, couldn't you add 4 more DVRs, and by adding a third cable to each, make use of the SWiM-16 to add DECA only to these 4 locations?

    "Seems correct".
    Keep the number of tuners at or below the SWiM limit, use coax from the SWiM to connect DECAs to receivers not on the SWiM, and keep the total number of DECA devices to at or below the 16 limit of the DECA cloud.
