    My understanding is that HDMI (or component) is active at the same time as S-Video when you are in 480i mode. He should be OK. (TiVoPony posted this information in a Yahoo forum a while back.)

    Except on HBO, Cinemax (coming to DirecTV) and Starz (coming to DirecTV), where the film is reformatted to fit your screen.

    So I am on the pre-order list for the hd tivo.

    current setup is as follows the triple lnb dish with line of sight to all 3 sats.

    2 Dtivos one in bedroom and one in Living room
    So one side of the condo has 2 cables going into living room
    the other side has 2 going into bedroom. So the 4 from the dish are split in 2 directions.

    When I get my new Dtivo what will I need to do? just disconnect the DTivo in the living room and connect the 2 cables to the HDTivo?


    What am I missing?

    I am pretty new to the HD stuff. thanks

    Yes.

    If you want to be able to receive local over-the-air broadcasts, you'll need to install an antenna and either wire it into one of those coax lines using diplexers, or get a 5x4 or 5x8 multiswitch (and a diplexer on the receiver side).

    If you want to retain use of the DirecTV DVR in the living room, simultaneously with the DirecTV HD DVR, you'd need to add 2 more coax lines from the dish to the living room and install a 5x8 multiswitch at the dish.

    Thanks Doug.

    That sounds great so minimal interruption then. I can pop the antenna up there and get the diplexer and have the new reciever up and running without any more cable runs.

    I have no need of 2 Tivos in the living room.

    Wrt to OTA shows broadcast will I need that or will the NBC/CBS/FOX locals etc all be broadcast in HD by DTV. Or is that related to the O&O stuff I have been reading about.

    There is no room on the DirecTV satellites to have 30 copies (or even 3 for that matter) of ABC, NBC, CBS, PBS, UPN, WB, or Fox in High Definition.

    Digital TV stations come in over a rooftop antenna or rabbit ears.

    Not necessarily true.

    CBS-HD East and West is available on DirecTV and DISH today.

    FOX-HD is coming to DirecTV.

    There is rumor that ABC And NBC are not far behind.

    Of course, all the above is if you have a waiver from your local affiliate that is NOT an Owned and Operated (O&O) station by the network.

    See the AVS Forum for more details.

    duffin,

    I am sure DirecTV will eventually get there. But as of now, they do not have enough bandwidth for all those channels, and that's a fact. The only reason people are saying those things is because of the immenant launch of the new DirecTV 7S satellite (which is pushed to April, I think), which is hoped to create more capacity.

    In the mean time, your best bet would be an indoor/outdoor antenna.

    Hong.

    I agree they don't have the bandwidth for local affiliates in HD, but they DO have the bandwidth for East/West HD national feeds for distant customers if they so choose to provided them.

    NBC, ABC, FOX, WB, UPN, at least... That would be 10 more HD channels. I doubt they can do that without dropping others. For me, I'd rather have them put STARZ-HD or BRAVO-HD on. But you might feel different.

    I have a question regarding the tuner architecture of the HD-DVR250 -- not sure if anyone will have enough info. to answer this, but here goes:

    I live in a new midrise condo with about 50 units and a rooftop satellite system that a private contractor has installed with a pretty complex distribution system inside the building, including mixing a rooftop OTA antenna into the HD feed.

    The pre-wiring in the building into each unit is limited and can't be expanded because of physical access limitations, and creates limits on how many feeds of what type can be brought in. Bottom line is that I can receive one feed to the back of the HD Tivo that will have all three satellites plus OTA, so I diplex the OTA over to the OTA input and have one satellite tuner active -- and I can live with that.

    There is a second feed cable available from my junction box to the prospective HD Tivo location, however. It's possible to bring a second HD signal over it, but that would max out the feed capacity to my unit overall and I wouldn't be able to get SD signals elsewhere (and I need them). I can, however, bring one more SD signal into the unit without impacting any of my other feeds, and I could feed that to the back of the HD Tivo into the second satellite port. (I've researched this carefully, and these are the limitations due to the way our building distribution system is set up).

    OK, here's the question: will the new Tivo work with one HD signal into one satellite port and one SD signal into the other? This would allow me to use dual sat tuners with the limitation that only one could get HD. My concern is that the guide reference might be common, or the unit could have a problem with only the 101 satellite being on the second tuner -- or some other issue that would give it problems with this mixed satellite setup.

    Anybody have enough insight into the way the unit works to know if this will fly?

    Thanks for your help.

    I don't understand why you are drawing a distinction between SD feeds and HD feeds. You have satellite feeds, and OTA feeds, both of which could be carrying SD and/or HD content.

    Darin, it has to do with the way the main building distribution system and multiswitches are set up to serve 50 units -- all owned by a contractor who designed the distribution system. The building was built with only two coax feeds into each unit: no way to snake more coax into the unit from the distribution system, and the multiswitches are somewhere else and I can't get to them or modify them (and I'd have to snake more coax for that to work anyway).

    The options are: two HD, going to two tuners, or one HD and one SD. I think the SD must be "stacked" so that it can be split to up to four receivers. But the HD isn't "stacked", so it can only go to one tuner. I have three SD receivers and one HD right now. So my only option (without taking down my other SD receivers) is to split out the fourth SD signal on the SD feed and connect it to the second tuner on the HD-DVR250.

    Does that clarify it? When they built this building (only a year ago), if they had understood the technology they'd have run four coax lines to each unit, and that would have created a lot more flexibility.

    No, I am still not clear. There is no such thing as SD or HD feeds. As Darin said, there is only Coax. It is where they are hooked-up that matters. So, you need 2 coax feeds that come from the satellite and 1 from the OTA antenna. The OTA can be diplexed in and out of one the satellite feeds so you only need 2 coax in total.

    Now, this may be your real problem: where are dish are the feeds coming from? Perhaps the "SD feed" that you are referring to is hooked up to an old single LNB dish. If so, it's a matter of cascading or upgrading the multiswitch so that it is hooked up to the right dish/dishes.

    Even having run four coax lines to each unit is no guarantee for the future; when there are yet additional satellite feeds to make available, such as the SpaceWay satellite signals, or Ku/FSS signals, both of which might get utilized by DirecTV for new services, then you'd be stuck unable to use a multiswitch in your unit if you needed/wanted any of those new signals.

    As I gather from your description, you have 2 coax lines from a triple-LNB distribution system and 1 coax line from a stacked 1-LNB distribution system... right?

    If you do have the 2 triple-LNB coax lines, and 1 stacked single-LNB coax line, you can utilize a cascadable 5x8 multiswitch and make the full triple-LNB signals to all receivers in your home.

    The stacked cable would provide the two SatA inputs to the multiswitch (after destacking them), and the 2 triple-LNB coax lines would provide the two SatBC inputs to the multiswitch. And you'd diplex off the antenna signal from whichever cable it was available, and connect that to the antenna input of the multiswitch.

    You'd have a mess of wires around, especially if these coax lines came into different rooms, but you could do it.

    Ok, I think I understand now. Since you mention stacking, I'm guessing that what you really mean is that you have the option of two feeds that can get all three satellites, or a stacked feed that can serve 101 to multiple receivers, plus another feed that can serve all three satellites to one. I don't know if there is a stacker/destacker solution for multiple satellites, so this would make sense. Historically, most of the HD has been on the 110 and 119 satellites, so I could see how this confusion could exist.

    So really, your options are: Give the tivo two feeds and let it run dual tuner, or give it it one feed, and have another signal that can feed the other receivers you have. Obviously, you want to take advantage of dual tuners on the hd-tivo, but you also have other receivers that you want to serve. THAT is your quandry, correct? You could feed the second tuner of the hd-tivo with the stacked signal (which could simultaneously feed the other receviers), so it would see all three satellites on one tuner, and just 101 from the second, but here is the problem: assuming the HD-tivo is like the current SD version (which in this respect, is a pretty safe bet), you can't differentiate between the two inputs as to whether or not you have a single sat dish or a mult-sat dish, nor can you give each input different "channels I receive" lists. So you'd have some channels (MOSTLY HD) that could only be seen from one input, but it would sometimes try to tune those from the other tuner, and it would get nothing. It would be a problematic setup, that would kinda work, but have some annoying problems.

    There is a third, though expensive, option. Since you have two feeds coming in to your unit, you should be able to stack BOTH of them, so you can get all three satellites on both feeds. Since you say you have the option of a stacked signal that can feed multiple outlets in your unit, but only two feeds that come in to your unit, then they must split once they get to your unit. IF you have access to where those signals are split, then a second (somewhat expensive) stacker could be put downstream of the multiswitch, with a 22khz tone generator that makes sure that the stacker is always asking for the combined sat B/C signal. Then in your unit, use a destacker to break it back out into the odd/even sat b/c signal, and take another destacker to break out the odd/even 101 signal, then take those four outputs to feed a multiswitch, which would then have outputs to feed each of the outlets in your uniti all three sats. I've never heard of this being done, but I see no reason why it wouldn't work. Stackers aren't cheap, but neither is the hd-tivo.

    And the difference between what Doug is suggesting and what I'm suggesting is dependant on what you have coming in to your unit. I'm assuming you ONLY have two cables feeding your unit, and you can choose whether you want them to be a stacked 101 signal, or a non-stacked triple-sat signal.

    We really need to know more about how the wiring is set-up. Do the individual outlets in your unit go directly to a distribution room that has access to everything, or do you get two feeds to your unit that are then split?

    Yeah, re-reading I think you're right about what he has... 2 cables.

    If he could get a cooperative neighbor with a common wall to feed him their triple-LNB signal, he could feed one (or more) of his multiswitched ones back so the neighbor doesn't lose anything or has a net gain and he gets expandability. ;)

    Getting the contractor to stack the SatBC signals would probably be the only other alternative. At least it wouldn't be totally expensive since half the stacking is already done (SatA).
