    Since they are outed in the FCC filing, how long before they are formally announced?

    Doesn't Apple usually not have the FCC filings released until Apple is ready?

    1.5 seems really short especially considering drives are about 26mm or 1 inch.

    It doesn't leave much space for airflow over the surface of the drive.

    The Premiere is 2.4" per the TiVo page.

    It does make sense if you think about it though as far as the size being the other away around. The 4 tuner probably needs more space for the OTA parts.

    TiVo doesn't typically announce these things. They usually just lift the media embargo and put out a simple press release about a week before they start selling.

    So I think Richard didn't quite interpret the FCC filings correctly... there are really three boxes... here is the comment I posted on engadget.

    Just supplementing sbiller's figures:

    From the annual report,
    "At February 28, 2013, we employed approximately 576 full time employees, including 50 in service operations, 354 in research and development, 51 in sales and marketing, and 121 in general and administration."

    So that means they probably have around 100 consultants/contractors in their R&D side in addition to the full-time folks above.

    Note that TiVo has always regarded itself as a software engineering house. They have never wanted to be in the hardware business, and still don't. But the unexpectedly poor reception of DVR's upon introduction forced them into the business, since there wasn't enough money for the big hardware folks like Sony, Phillips and Toshiba to remain interested.

    I would guess just the audience measurement side of TiVo has more software engineers than the 5 postulated here for all of TiVo.

    The hardware does NOT support it. That's the point.

    An 8 bit number can't hold a number greater than 255. That is a very simplified analogy of the problem. The existing limit is the MAXIMUM size that the filesystem supports.. So it would need a new or tweaked (changed) filesystem to support bigger sizes.. or somehow be able to add more partitions (though I suspect the partition limit is involved in the same kinds of limitations I describe.. maybe there's only 4 bits for # of partitions?)

    The Weaknees is "just" 2 drives at the maximum married.

    Which means that the filesystem can support 4TB. Logically, the drives are treated as one volume.

    The limit is 2.2TB (Or 2TiB) per drive, so the maximum that the current Premiere DVRs can address is 4.4TB (Or 4TiB). The external storage solution that is used bypasses the kernel limitations but still maxes out at 2.2TB (2TB).

    And that is my point. It s a Linux kernel limitation, not a filesystem limitation. There is also a possible disk controller issue in the current h/w. I seriously doubt that the TiVo MFS maximum volume size is smaller than that of ext2, which is 32TB.

    According to the mfstools source, the MFS volume header (aka superheader) uses an unsigned 64-bit field to hold the total number of sectors. I use the same structure definitions in DvrBARS.

    Even if you assume that it's actually a signed number and that a sector will always mean 512 bytes, that's almost 4 zettabytes. I don't think the current MFS filesystem poses any practical limitations.

    One diagram indicates the width of the box. The other diagram indicates the dimensions of the back plate or label.

    Interesting that the arched model has one AV breakout - wonder if it's for composite, component, or both. I'm guessing composite only and that only the higher-end units will feature component.

    (For reference, my Premiere looks to be 16.5" wide and sits about 2.5" high.)

    Update: Looking at the design notes, AV was "composite" until about April - so that suggests only 6-tuner is component.

    Ah, I see now. The diagram even indicates vinyl with PSA backing. Derp derp Jim.

    You're probably right about the A/V socket.

    The report and labeling doesn't explicitly mention MoCA on the SFF box. I know they're making this box as inexpensively as possible, but that would slightly suck since one would think they'd make that a standard, at least as a "client" like the Mini if not with full-blown ethernet bridging. It's already on the chip... Hope they have it.

    The other report stating MoCA is only on the Pro and not the Plus doesn't compute with the moca alliance certificate. Sure as hell hope they're wrong on that. LOL.

    I'm surprised the 4-tuner box doesn't have the MoCA label on the coax port since I think TiVo's MSO partners would demand it for their WH installations.

    Also agree that the MoCA Alliance certificate is assigned to the Plus unit and the FCC report indicates the hardware is identical. The only thing I can think of is the Plus unit is using a pin-for-pin identical Broadcom chip that doesn't include the transcoding and/or MoCA support.

    If they truly have dozens of software engineers, they are literally the worst engineers ever hired by any company and the hiring manager should be fired, hired again, then fired again just to be sure.

    Eh, MSO partners wouldn't require a box that also does OTA. Perhaps they'll keep some Premiere variants around or rely on other Pace hardware. Hm.

    My question would be is there enough savings between a 4 tuner box and 6 tuner box to justify a cable company messing with it?

    On the other hand if the 4 tuner box was designed to be a stand alone only box (not the Hub of a whole home system) like the current 2 tuner Premiere maybe MoCA wouldn't be that much of a benefit.

    Good points... that appears to be the strategy. The 6-Tuner gateway boxes (Pro/Plus) and the base 4-Tuner stand-alone box. If the Plus price point is low enough it makes even more sense.

    That seems really dumb. While I'd love to have the 6 tuner box, 4 tuners is enough for almost everyone. It seems nuts to force people to buy the 6 tuner box for whole home.

    We have found that, for whatever reason, folks with Tivos still watch live TV a significant amount of the time. So, a 6-tuner box makes sense for whole home so that the minis can provide this.

    I never watch live TV but during NBA season I need at least 5 tuners just for myself during primetime, so a 6 tuner unit is very welcome and I'll be 1st in line to get one (also expecting HDUI and flash apps to run MUCH faster than the current horrible experience of the Elite).
