    Winters,...
    There could be several reasons why two Genies aren't allowed; there could be one reason, or none. But for now, it simply isn't in the cards, though I predict that it will be some day in the not distant future.

    When we upgraded to the HR34 Genie, DirecTV allowed us to keep our existing HR24 DVR, so we moved our existing DVR to the master bedroom (we previously had an H25 there). That totals to 7 tuners. Not sure if DTV will allow a Genie and two HD DVRs.


    I've got a Genie, (5) HDDVR's, & (1) client. No problem with DTV.

    I think that it's inevitable that some households will be multi Genie households in the relatively near future. I think that customer demand will dictate that. I think that two tuner DVRs will be old technology within two years....some would argue that they already are.

    My Genies can see each other, yes. However seeing each other and behaving well together are two different things.

    I don't think cost would have have a made a huge difference between 5 or 8 tuners.

    The only reason I keep harping on an 8 tuner Genie is that if D* wants to have only one DVR serve the whole house that share tuners with clients then it should have added those 3 extra tuners. It also makes for an easier one cable installation on the current SWiM 8's.

    I think one day we probably won't have to worry about recording tuners, everything will just be in a cloud somewhere.

    Seems to me that at some point it makes more sense to move the tuners out of the receivers. Rather than requesting an entire transponder's worth of channels, receivers would request a single channel, and receive the MPEG4 stream for that channel already tuned, making all receivers/DVRs effectively clients at that point. The stream would be displayed via HDMI, or saved to a hard drive in a DVR. The tuners would be in a new LNB or multiswitch, which could also send out traditional SWM channels for backwards compatibility. New installs wouldn't even need coax, at least not inside the house. They could be connected via cat5 or wireless.

    If they're going to make any changes to the technology (even if it is just a SWM 2.0 that handles more tuners than today's 8) they might not bother to update/replace the Genie until that's ready.

    You are confusing the paper spec with the real world.

    Is the hard drive in the Genie still a 5400 RPM drive like it was in the regular DVRs? Regardless, a typical current gen 7200 RPM drive can only xfer a sustained 140MB / sec. SATA was 150MB total bandwidth. SATA 3 is 600MB / sec. Ok, so what? If you plopped a SATA 3 hard drive in, you aren't magically going to get 600MB / sec. You'll still get closer to 140MB / sec because that is the mechanical limit of the hard drive.

    The fastest SATA 3 drive on the market today is the Western Digital Raptor which is 10,000 RPMs. That's can only xfer 165MB / sec.

    If you went to a 15,000 RPM Enterprise Level HD, you'd still only get 223MB / sec on the fastest hard drive on the market today. Too expensive to put that drive in a DVR and it would likely run too hot.

    An SSD, the fastest on the market today is only going to give you 390MB / sec. BTW, the drive that can do this is only 512GB and costs $500.

    Theoretical connector spec bandwidths are meaningless in the real world.

    He was talking bandwidth constantly on reasoning. As I said, bandwidth isn't the issue,its can a hard drive sustain it speed wise ad such, as you just pointed out. Many are rated for ten to 12 streams which would be the edge of a probably bigger genie. I think a proper expectation would be a 7 tuner unit with maybe four outbound streams plus one Video On Demand. (That 8 th tuner would be for guide data, I don't see them going beyond two four tuner chips, which is really only two more tuners that what we have today) That's 12 right there. (11 if they stayed at three outbound) And again, that's assuming that they are all over the air to need that much. Realistically, no over the air, you likely have all streams under 8 I think. That's around 96... Well under the limits of a hard drive. The question is how that would all work with over the air. Most over the air is probably closer to 15 maybe? Been a while since I looked, so lets say 16. You can record a max 2 over the air channels right now, and send out as many as possible, so lets say they stay at 3 outbound streams, so add another 40 pushing you to 136. 144 if we push to four outbound. Its on the edge of reason. My guess is at that point the bigger issues is streaming four over the air signals at one time for the processing power to clients.
