    I've been told that when it's all said and done, DECA will be the solution that DIRECTV techs will install and that will be supported in the call center. Everything else is on the "not recommended" list .. BUT .. if it works, it works so a "commitment to support" is an argument in semantics and if that means .. yeah, they'll talk to you on the phone and do what they can .. then you're right, that will probably happen.

    Apparently "shoot the messenger" is en vogue.

    Now this I can agree with :) ;

    As I don't quite understand the logic behind DirecTV's putting MRV into a national release supposedly for a voluntary beta testing program in addition to or beyond what the CE subscribers were already performing, before releasing the DECA modules to market. :confused:

    How can MRV be fairly beta tested during this program without DECA?

    A good wired network will perform just as well as a DECA network does.

    lol: You are to true thank you sir: I humbly admit my error and will correct my spelling in the original post. I was just so hot reading this forum and some of the comments. I didn't proofread my own post. I still feel the same a fee is ok pay or not is always a choice. But don't make me buy your equipment when I already got the same thing working myself. I don't need tech support for the service to work in my home it already does. I'm paying DTV a fee already for each HD box, a DVR fee, a HD service fee a protection fee and etc. etc etc.. :grin:

    Wait, what are you saying VOS?

    That the ability of not having to rely on a home network's ethernet switch/router gear or not having bandwidth hogging MRV data transfers compete with other home network traffic by keeping all MRV data traffic isolated within the DECA cloud is not really a performance advantage over a conventional wired network that typically would have these limitations when running MRV?

    Guess this would depend on how much traffic is there.
    I've run both wired and [have] DECA and they've worked exactly the same.
    MRV is around 15 Mb/s, with trickplay peaking at around 35 Mb/s, which hasn't been any problem here.
    Using switches can keep the traffic out of the router.
    If your network is such that bandwidth is a problem, then DECA is a real solution.

    I'd be willing to bet that for most home 100Mbps networks any MRV traffic on there will probably not even be noticed by folks using the computers. I've had three MRV HD streams concurrently through a 100Mbps switch an a single uplink to another switch, a local Sling box session and ran a www.speedtest.net test from a workstation on my 18Mbps/2Mbps internet connection. The speed test didn't show any change from what normally is shown and didn't see any different performance on any MRV session vs. one only one MRV us being used.

    What are the limit that cause MRV to become unwatchable and how does the DECA improve it over a hard wired set up?

    I'm not sure those determinations have been made yet. I think a big advantage of DECA, as mentioned by Doug and others, is the fact that it is a supported product of DIRECTV. If it breaks, or isn't working properly - you can call customer support and they will be trained to help you. As to whether or not it can/will perform better than your home network remains to be seen.

    Here's a question - will DIRECTV2PC, like MRV - eventually incur a type of monthly fee?

    Oh well ...

    Guess the only real advantage of DECA then is eliminating the need to pull ethernet cable through the house since you can use the existing DirecTV satellite cable plant.

    But perhaps that alone is advantage enough for many people.

    Though I was hoping the ability to keep MRV data bottled up in the DECA cloud and separate from home network traffic would translate into a noticeable gain over a wired network. :nono2:

    This is probably true as long as the router and switch can maintain a fast enough continuous data rate. Don't assume that it will. The key is if it does work good for the most part on a standard wired network it's probably OK. That just may not be the case in every situation.

    DECA will do VERY WELL in situations where networking is new to the receivers. It's much easier to install in these situations.

    I can't say what the limit is since I haven't had/reached it here.
    What does seem to be important is maybe not "how much" but that "every bit" for MRV [and DirecTV2PC for that matter] arrive at the client at the right time, since this is streaming data and not file transfer.
    Internet traffic or transfer between PCs can miss a packet of data and simply ask the sender to resend it. With streaming, any missed packet doesn't get asked to be sent again as the client can't wait and must simply skip it and move on with playback.

    Unless something changed since the last time I did a packet trace with Wireshark they're using TCP/IP for the network protocol. TCP can/does handle missing/corrupted packets and if the receiver has a large enough buffer and the network is quick enough a packet can be resent and the view won't even notice.

    No one is trying to shoot you Doug, I am just trying to say DirecTV should support those who use their own networks for MRV, and the fact they are planning to do beta tests on people's own networks demonstrates they will support such arrangement. They may say if you want service guarantee, then only their own DECA connection will provide that. The entire CE program has been asking the folks with their own networks to test the MRV for them, to say now DirecTV has almost completed the test and MRV is ready to roll, those who did the tests for them will not get any support is unreasonable, especially when DirecTV has decided to charge a monthly fee.

    Of course you are just passing their words, we are just giving our feedback, nothing personal.

    OK maybe I was being too simplistic, but there isn't much buffer in the H21/23.

    From what testing I've down, for a HD MPEG4 program it's between 5 to 7 seconds, more then enough to get a retransmisson done on a 100Mbps network IMHO. Just look how fast a skip back get's handled and that's dumping the buffer and starting to send the stream over again.

    I've read your [good] posts, but sometimes I just try to make it simple so some can/will get the idea. :)
