    Huh? You mean like how they obviously can't sell a DVR that locks up frequently and doesn't always record what you tell it to?

    :lol:
    I kid, I kid.....

    Seriously, though, what's the alure of two live buffers? I mean, I get you could switch between two live shows without missing anything, but is that a really widely desired thing? Is it mainly some sports-driven need? I don't know abou that stuff.

    The dual buffer is a "must-have or I'm leaving DirecTV" for some people.
    For others, is something nice to have during certain programming periods (sports for example)

    Others.. (Like me), watch 90%+ recorded material and rarely use the live buffer(s), so it isn't "that" big of a deal.

    But IMHO, once they correct the current live buffer to not empty out when you go to a record program... IMHO, it is easy to implement the live buffers by start the recording on one, and toggle between the two.


    As for Wi-Max.... that is way down the road.. I think the Broadband solution for the R15 (and HR20) is a "general" broadband solution, not specific to Wi-Max. And until "pricing" and specifics about Wi-Max are released... I don't think we can connect the two yet (from a buisness sense)

    I was merly asking, whenver wimax or broadband is enabled, that they have no reason to not use the dual live buffers? because then, it frees up that 2nd buffer.

    A lot more goes into it then just that.
    But we will need to table that discussion until we see the implementation of the Broadband connection to the units.

    Think about it for a minute....

    You have a broadband connection... (be it provided by your own $$$ payment to an ISP, or it is provided by DirecTV for a fee or not for a fee)

    So... do you want your broadband connection flooded with VOD transfers?
    Do you want an option to disable broadband communication for VOD?
    Do you want to ask for a VOD now, to be downloaded over night, or be ready for the weekend?

    What if your broadband goes down?
    How much of your broadband bandwith do you want to use?

    What if you have VOIP, how can you terminate a VOD transfer if it is interfearing with your other usage...

    Now lets going into keeping that VOD transfer secure on the public internet.....
    then again, let's not.

    So it is not as simple as; Plug in RJ-45 and Ethernet adapter and boom you instantly have VOD.

    Better yet, go ahead and use both of the tuners that are already there, but only when the box is idle :rolleyes:

    Seriously: if the box can't find a few hours a day when it's not being used, then chances are the person using it has no time for VOD anyway :p

    In fact, it seems like it wouldn't even have to be realtime. Use a whole transponder for two hours in the early morning for this purpose and you could fill up that 60GB in less than a week.

    The problem is that D* wants the stuff it pushes to be available in a particular timeframe. For instance, they have a deal with NBC to make some network and cable shows available within 24 hours of airing, commercial free for 99 cents per episode. They need to keep that second tuner available to ensure that, so forget about a second live buffer.

    This also raises the question, however, of what will happen if you schedule two shows to record during the early morning hours. Will the r15 even allow that? Time will tell....

    If the DVR won't let the user schedule what he wants to schedule to record because D*TV has it's own "agenda" then it ruins the whole point of a 2-tuner DVR.

    "Additional" content should be sent/pulled during off hours and only when not in use. Now "not in use" may be more difficult to define...but if, for example, the channel has NOT been changed for 2+ hours - during afterhours (say after 1 or 2 AM), it's probably safe to assume that the "other" tuner isn't being used and it's ok to be used by the system for additional content. Turning the unit "off" is a sure way to tell the system that it's free to download additional content.

    Once they fix the buffer so that it does not clear when you put the unit into standby, I will be willing to start putting my units in standby when I'm not actively watching them. But for now, I leave my R15's on 24/7 so that I can always turn on a tv and have the prior 90 minutes available (I leave them tuned to different news channels).

    I would be very upset if the R15 were to change my channel to receive/record a pushed program. It should only receive a push when one tuner (the second, or non-buffered tuner) is completely idle. In other words, the buffered tuner is never idle, so it would only receive a push when you are not recording anything.

    Carl, I'm curious. Why don't you just set up a daily record of the news channel rather than leave your box on 24/7? You'd have your news, and the box could do its housekeeping more efficiently.

    Just a thought.

    Doesn't do much for breaking news. Also, I don't have set times during the day that I switch on the news to watch. It varies, so when I do switch it on, I will frequently scroll back to the nearest hour or half-hour point and catch the headlines, market status, etc. Then I turn the TV off for awhile. Then I might turn it back on a few hours later and do the same thing again.

    This is exactly where dual live buffers, even if they were only 30 minutes, would be perfect!

    I do record certain newscasts daily. But throughout the day I catch snippits here and there as schedule permits.

    I guess it's not that easy. Does everyone want or even needs VOD at all?

    The counter question:
    Does everyone NOT want or need VOD


    For both of those questions... the answer is no.

    Teays...
    But D* wants you to have it, so you WILL get it whether or not you want it OR need it.

    Earl,

    Question on your conversations with your contact: The dual buffer something they know we want, but is it something they really don't want to give us for some reason. Or is it too big a project for now given the other fixes they need to implement?

    They're going to have to have it on the HD DVR because everyone that has the TiVo version now will be expecting it when they upgrade to get the MPEG-4 channels.... At least I will. :)

    As for size of the project, ect.... I don't know.
