    I am starting this for the First Look.

    Please post your before and after results.

    Also, please post your "before" Networking setup. (wireless, wired, powerline, etc)

    Please do not clog this thread up with discussion.

    I was on 100 Mbs wired connection before hooking up on DECA. Shows seem to start faster after hitting "play" than they did on my wired connection. Trickplay for me is definitely snappier. When using trickplay and FF(at all given FF speeds) to the spot you want, picture and audio comes up right away with no delay like on my wired connection. So far on 15mins of play on an HD movie, there has been no pixelation or audio drops(keeping my fingers crossed that it will continue. MRV is way better so far with DECA than with my wired connection.

    As far as MRV performance I'm not seeing any difference. Playback breaks up and shows pixelization the same whether the recording is on a machine on the DECA network or on my regular network. And trickplay is the same as well. I'd compare it to the way trickplay was on the HR20's in 2006.

    That's a bit surprising. I would expect to see an improvement.

    Wonder if we need to reboot things (including the SWM and devices) to actually see the full performance....we'll await a "ruling" from one of the experts.

    I powered down everything to hook up the DECA stuff so I don't think a reboot is going to help.

    I did not power my equipment during install, nor did I reboot any receivers after the install. Not sure if this matters, but I am not using the two-way splitter D* sent. I hooked up the DECA PI to an open port on my STS-4.

    Why?
    Each receiver is limited to 100 Mb/s output.
    Even though the DECA might be faster, a good hardwired Cat5 is going to be "the same" @ 100 Mb/s.
    "You wireless" folks, should see an improvement, but "us wired" folks shouldn't.

    It doesn't matter, you just simply did not need the splitter.

    But I'd have thought any pixellation or image degredation would be pretty much like a straight cat 5/6 line result - virtually none.

    I hardly get any on my wireless...would think the MRV stuff would be bnearly perfect with the new setup.

    This just "proves" the random glitches [in MRV] have zero to do with "my network" [which I've been saying from day one].

    I see no difference between DECA and wired LAN. Occasional / random pixellizations on both.

    Why do you think that? I've tried a direct connection between a HR23 and H21 and I saw no difference on how MRV performed, still say the video 'glitches' and trick play issues. And also folks with DirecTV2PC have reported not seeing the video 'glitches' when viewing the same program from a PC over their ethernet network.

    Maybe if the pixellation and degredation were because of networking issues or log jams we'd see a difference but I'm thinking the issues we're seeing with MRV playback aren't network related.

    My MRV performance is basically the same as before.

    The only problem is slow trickplay, scrolling, startup.....

    No break-ups to report, yet.

    Yep, that's pretty much it.

    Was hardwired before and 802.11n @5GHz before that. Can try any combo that is desired.

    Because it seemed strange that my wireless setup is having less of these pixellatoin episodes that folks with wired setups. I assumed that this new configuration with DECA would result in even better results.

    Obviously..there are some firmware issues tied to MRV too.

    No networking before.

    After installation, connected and worked fine. Started playing a in progres recording from HR20 in the other room. Played glitch free for 5 minutes, and froze. Screen just sitting there on a freeze frame. Info brings up banner. Play brings up scroll bar showing its playing, but its not. Time bar even updating like the box thinks its still playing.
    Stop and resume finally restarted the program.

    Deca lights showed good during this time.

    PIG (of MRV) breaking up badly while trying to send report.

    EDIT: Went to HR22 and attempted playing the same program from the HR20, and it did the exact same thing on the exact same frame, so Im guessing its not a bug, but a glitch in the original recording.

    I did have one STB connected with a WGA600N during testing and that connection saw the same issues that my wireded boxes did (which I guess could be because the servers were all still wired). Thing is that the box really doesn't care what type of network connection you have. If you configure a wireless adapter on a PC, so you don't use the GUI to configure it, a powerline adapter, wired or the DECA box it don't know what the transport really is.
