What are your thoughts on Dual Live Buffers?

  1. DLB's are not an important feature to me, based on my use of the HR2x.

  2. I might use DLB's if implemented, but I can live without them.

    They do know it, as I stated before and I'll state again, it is clearly indicated in the i-guide manual as a feature - there is a button on the remote called "swap" which is dedicated to DLBs.

    Dude, at least pay attention to my points. With regards to what I posted, your responses make absolutely no sense. :nono:

    DIRECTV doesn't CARE about me anymore??? I am crushed!!! I thought we had a great ongoing relationship. Directv, how could you be so fickle after all the money I have given you??? I WANT MY DLB and I WANT IT NOW!!!

    Just curious, is that "swap" button for the PIP screens, or actually for the DLB?

    I'm not sure what it does if you are using PIP. I used the 6416 over the summer when we lived at a place temporarily while our house was being built - so I no longer have access to one.

    The info for the DLB is here (the guide may say something about PIP as well, I have not been through it to see):


    "Because your DVR has two tuners, it can buffer two programs at the same time – one on each tuner. The SWAP feature lets you toggle back and forth between the two live shows while giving you full control of both.
    While you are tuned to a program, press the SWAP button on your remote.
    • You will change tuners.Now you can select an alternate program by changing channels or using the Guide.
    • Press SWAP again to toggle between the two programs.
    Note: The SWAP button is the key to keeping the buffer for both programs. If you change channels without using the SWAP key, you will lose the buffer."

    Sure wish we had this control back with D*- Can't understand why someone would consider this undesirable...

    This is just my opinion but I don't think Directv considered it undesirable.

    I think it conflicts with or takes resources from and existing/future feature. They had to make a choice and DLB lost out.

    It's a theory....:rolleyes:

    Too BAD that Directv doesn't let us know why they can't or won't do DLB!!!

    Every so often, Earl and I post some of the reasons why DLB is not in the DVR+ line--today...

    1) As a brand new line of receivers, version had to have certain features first. DLB was not on that first cut of features.
    2) After that, feature selection is based on many factors: upcoming TV programming requirements (support for new ideas for hotpass, MLB, NFL, etc.); pre-requisite coding under the covers; revenue making requirements; investor promises; software development team availability (with many teams, sometimes a feature waits until all the teams finish their parts)
    3) DIRECTV has heretofore felt they have features we'll love even more first. They are in progress and sound cool.
    4) making SLB very, very solid. Raising twins is not twice the work of raising a single infant--it's closer to quadruple. Similarly, I bet any SLB issue that is outstanding is quadruple the magnitude in a DLB environment. :)
    5) resolving all the logistics and interactions between features that use the resources within the DVR: tuners, memory, disk, cpu, processes, scheduling, etc. Think about all the features that do or will use tuners for a moment: Guide, recordings, SLB, showcases, pushed DoD, channel mapping updates, weather and other interactive content, etc.

    Richierich, one reason we won't see specific "this is why you do not have DLB" is that reason is not just one "permanent reason" but a normal shifting of the requirements and development resources as features are released and stabilized.

    Can I say definitely DLB will be here? No. As I said, things are always in flux.

    I can say that I believe DLB will be here. And thinking positively, trying to attract a future of my choice, DLB will be here and solid before the NFL season starts up again. :) (That is a personal hope, prayer, and attempt at thinking positively, not a hint.)


    All this very definitely can be worked out in a reasonable fashion. And DIRECTV has not taken DLB off the table. They very definitely listen to us.

    I work in the IT / software development industry and I agree with all of the very logical rationale that you outlined, however, just to play devil's advocate for a minute... Sometimes the problem of adding a feature such as DLB might become technologically very difficult if it is added at the end once the underlying single (SLB) feature set is fully developed. The added complexity of course may not fully materialze if indeed DLB was part of the general design all along and no design decisions were made to make the eventual DLB development more difficult.

    Or more simply... sometimes you just can't do it unless you designed it in from the start, or you start over from scratch.

    Hopefully that's not the case for DLB on the DirecTV DVR platform. But for me personally, can we please have MRV soon? :D

    Again it's not just TiVo that has DLB.

    List of DVR with DLB.

    TIVO line.
    AT&T Homezone DVR
    Dish Network – ViP622
    Charter Communications – Motorola (Moxie BMC-9000 series) and Scientific Atlanta (Explorer 8000HD).
    Cox, Comcast, Adelphia, Time Warner – Motorola (DCT-6412 & Moxie) and Scientific Atlantic (Explorer 8000HD)
    MetroCast – Motorola(DCT-6412)
    CableVision/Optimum – Scientific Atlanta (Explorer 8000HD)
    CableOne – Motorola (DCT-6412)
    FiOS – Motorola(QIP6416)

    I think DirecTV plus line is the only one without DLB.

    I have asked before but just want to make sure ( Inever got an answer ) . Are they planning on pushing DOD on the second tuner ? If so I will be real pissed that is the reason for no DLB .

    As Tom said, their reasoning is constantly changing. One thing you can be sure of is that some very powerful people read this thread and are aware of your desire for this feature.

    My guess is that DoD does need to use the second tuner, unless they figure out a way to intermingle guide and DoD on the third tuner.

    That said, recall my postscript: "All this very definitely can be worked out..." :)

    "Daddy, are we there yet ?"..... hehe

    I also feel it will be implemented but it most likely wont be fast enough for some of us. I think D* has their schedule of features laid out and the time frames they plan to implement each one and are going by it as closely as possible but as Tom said in different words "things happen". When they do D* has to be flexible in order to keep us with a solid SLB or all of us would be screaming.....I believe our patience will be rewarded

    Tibber, I want to thank you for the most thorugh response to this issue to date. I have to believe, knowing what a selling point DLB is for the very lucrative season passes, that they maintain it on the radar...

    It seems like the ground work for DLB is already there. The only difference I see between the buffer and a recording is the recording gets saved and the buffer doesn't. Take the current "work around", don't save it as a recording, and you have DLB. They already added the "keep pause" function. Now all we need is a button to go back and forth. Doesn't "seem" very difficult to do. The only thing I would consider as an acceptable reason to wait on this, is if they do some type of split screen where you can watch both tuners on the same screen at the same time. Dual tuner PIP from one video source on any TV would be sweet. DLB would of course be needed for this.

    Correct, and what does that tell you?

    If D*'s service and set-top box are the best-in-class and it doesn't have DLB and all the other inferior services' set-top-boxes have DLB, then DLB is the problem. It's what holds back a decent STB and makes it weak.

    The elimination of DLB is the wave of the future; don't blame D* because they figured it out first. All these other providers will learn from this and eliminate DLB too. Years ago, all phone manufacturers felt that the rotary dial was the best solution to make a call. When the push button came out, all the RD people screamed "we want RD back!" but ultimately came to realize that PBD was the better solution. You don't hear from those RD people any more. They were never part of PBD nation. They all died. Just like DLB.

    You're assuming that the Directv HD DVR is best in class. That is a major assumption. It is a good box but on the software side many think its a step back from the HD TIVO. My wife constantly curses the way many of the menus and button press schemes on this box work and constantly asks why we needed to "upgrade."

    To say that DLB holds back other boxes is very naive. It absolutely is not the wave of the future. Directv misjudged how near and dear this feature is to their high end sports junkies and are likely scrambling to come up with a fix.

    If everything was equal with regards to HD content and Sunday Ticket you'd see how many defections would occur. Or if Directv were forced to open up their receiver market a la cable card, a new HD DirecTIVO would totally outsell err out lease the DVR+ to many on this site.
