    Just got my unit and plugged it in in no time. Activated with DirecTV and got my HD programming going. I set up a Zenith indoor ATSC antenna and got 90% on my OTA channels as well.

    The only problem is, though S-video looks perfectly crisp, component cables in 480i, 480p, or 1080i look like bad MPEGs. The text is all blockly like a VCD would look.

    Any help? I'll try different component cables tomorrow, but that input on the TV works perfectly for other devices hooked up with component cables...



    UPDATE: I turned the noise reduction and sharpness all the way down and now the picture is perfect on the component connections! Thanks to all for the responses.

    It might have something to do with your display's native resolution - does it conform to what it's given? The s-vhs input will always be 480i and the display will know this, but on component it might be locking the resolution??

    Quick question.
    I have 2 feeds coming into the HR10-250 from the sat and I selected the 2 input option during the initial setup, but I am continually getting scheduling conflicts when I change channels while it is recording what I am watching.
    What gives?

    Do you have suggestions or Starz On Demand enabled? Is it possible it's recording one of those on the other tuner? Are you completely sure you don't have two things scheduled to record? Try doing a down arrow to swap tuners and see if the other one is recording something then this happens.

    mercurial,
    Thanks for the response.
    Yes, I have suggestions enabled but no Starz. Should I turn 'suggestions' off?
    I will give that a try. If only one thing is being recorded, does the HD-Tivo automatically switch to the 2nd tuner when I change channels or do I have to manually instruct it to do so?

    Well, I turn off suggestions personally. With all the extra recording space, it just makes for too much stuff in the lists. I go and look at the suggestion list now and again and pick some thing to record. So that's a personal choice. If you turn know it's a suggestion being recorded, you can just abort it if you want to watch something live. The only downside of that is you probably end up with a "partial" recording in your list.

    If the second tuner is free and the current tuner is being recorded and you change channels, it should switch to the second tuner automatically. The down arrow (or LiveTV) button lets you toggle between the two if you're curious what each one is doing but you don't *have* to do it to make it work.

    Aborted suggestion recordings are deleted from the Now Playing list automatically. Aborted explicitly configured recordings are left there.

    Hi everyone,

    I'm new to this site, and I just wanted to get your opinion. I have a Sony KF50-WE610 (LCD widescreen) TV. It only has one DVI input. Currently, I have it hooked up to my Samsung HD-931 DVD player (which I bought solely because it had a DVI connection). I just got the HR10-250 yesterday. Obviously I want the best pic resolution possible. So do you guys suggest I use the DVI input on my TV with the DVD player or the receiver? In which case I would use component video on the other.

    I read somewhere that the HDMI/DVI connection on the HR10-250 can cause some wash-out on some TV's, but just wanted to see if anyone else has run into this issue and what you did.

    Thanks.

    I just helped a friend install that same Sony LCD TV and we connected his new HR10-250 via DVI. It looked spectacular. His HD TiVo is replacing a Hughes HD DirectV set top box and the TiVo looked every bit as good as the Hughes it was replacing.

    Given the choice, I would hook up the 480p progressive scan DVD player via component and reserve the 1080i capable HD Tivo for the DVI port on your Sony.

    Of course you could always set the devices up either way and then swap them before you make the final call on what works best for your situation.

    I am having trouble getting information out of all of the Direct TV support personnel as to whether the HR10-DVR-250 can support a Wide-band input.

    I have access to Direct TV and Terrestrial HD through a distributed system installed in the condominium building in which I live. There is one huge dish on the roof, and apparently local terrestiral HD is modulated into the system from a yagi on the roof too.

    I also understand that the terrestrial HD is modulated in such a way that only Direct TV receivers that can accept wide-band (like the Hughes HD-HTL) will work in my building.

    Does anyone have any idea whether the Direct TV HD Tivo can do this?

    You are getting your DirecTV signal stacked. You only need a destacker to separate the 2 signals. The problem is that you're only getting signals from one satellite so you won't be able to get to 2/3rds of DirecTV's HD programming, since it's evenly spread right now across all 3 satellites.

    The terrestrial HD is just included on the same cable; it's highly unlikely it's being remodulated in any way; that'd work with a regular diplexer to separate the stacked signal from the terrestrial signal.

    But your main decision is figuring out if you can live with satellite HD channels only from the main 101° satellite.

    dswallow thanks for the reply.

    A couple of questions and confirmations:
    1. You are correct that Terrestrial HD is on the same cable. Currently, all I need is a diplexer to split my signal to access the terrestrial.

    2. What is a destacker and where do you normally get one?

    3. As I understand it currently, the building which has the stacked Direct TV only has regular Direct TV (so the only HD program accessible at the moment is terrestrial). Apparently something has to be added to all the risers to get a full HD system. So all I want to do is ensure that if I buy the HD Tivo, it will work on the existing system. It sounds like the Hughes HD-HTL has an internal destacker, and you are telling me that the Tivo does not have one internal, but I can just add one to the signal path between wall and the HD Tivo and I should be good to go?

    A stacked signal has the 2 signals (odd & even transponders) from 101° combined, with one set of them block-shifted up above the first set (which'll be the 950MHz-1450MHz range). A destacker just does the opposite, providing either 2 distinct outputs, one of each group of signals (and then requiring a multiswitch), or combining the functionality of a multiswitch to allow the one output to be connected directly to a regular DirecTV receiver.

    You should be able to get it through whoever installed that system, or whoever manages it. But you can also pick them up online, such as from http://www.9thtee.com/dssstuff.htm. The receiver you mentioned simply has this functionality built in. To enable both tuners, you'll need to provide two outputs for the receiver; so that means either destacking to separate outputs and using a multiswitch, getting the destacker with 2 receiver outputs, or getting a high frequency splitter and 2 destackers each with 1 receiver output.

    You will be able to get the HD material broadcast on the 101° satellite, which is mainly just the CBS feed (if you qualify to get it) and 2 NFL HD feeds. My guess is at least some of whatever new HD channels DirecTV adds will end up on 101° as well, since that's where they're freeing up space currently used by locals. But you won't be able to get HBOHD or SHOHD or the HDNet channels or DISCOVERY HD without signals from 110° and 119°.

    thanks again for the understanding. The local personnel responsible for the building had a disincentive to share this information because it removes the need for the condominium to purchase $10K of work to rewire the condo system.

    Now I know personally, I can use a destacker and use any box compatible with direct tv (not just those with an internal destacker like the HD_HTL).

    Curiously, as I make the decisions for the condo, they have stated that at minimum, to carry Direct TV's HD channels (not just terrestrial/OTA), we need a second run of cable into the risers on each floor. Additionally they state that you then need an extra run of cable for each HD box you use beyond one. I don't know enough about stacked systems to understand the riser one (but from what you stated, I would hypothesize that to turn the condo into HD, they need a second satellite, so this new run into the risers is just carrying the new satellite signal into the multiswitcher/stacker in each closet), but their advice about needing a second run of cable if you have more than one HD tuner seems specious. You could destack a single cable feed multiple times depending upon how many tuners you have rather than having to have a direct line from the riser closet.

    Perhaps this sounds like blabber from someone who knows enough tech to sound dangerous, but really has no such background, or maybe I am on track here?

    Yeah, they'd need to at least run another cable to everyone, where they could stack the remaining 2 signals (a combined 110°/119° odd & even), then those people needing those signals would destack the 2 signals from that cable and connect all 4 destacked signals from the 2 cables to a 4xN or 5xN multswitch to feed their receivers. They would need 2 more satellite dishes as well, since it sounds like they use a larger-than-normal dish, and one of those would require a special LNB since the 110° signal gets shifted a bit before getting to the receiver.

    Such is life; if a company commits to feeding a complex with the signal themselves, they need to be prepared to accomodate technological changes, too. :)

    After spending a good amount of time in the community studying tone generators, I think I fully understand what you are telling me.

    1. Given the way HD works, you always need two lines minimum to carry HD signal since a set top box can only call for channels one of two ways: voltage differential, or tone differential. (I assume all current HD stb's including the HR10-250 has its own tone activated switch)

    2. The way a stb calls for channels on 101 is exactly the way it is called for 110/119, thus you can't run it all on one line, but need two lines to do so.

    3. However, in a condominium setting, what you could do is run the second line into the master cable jack junction point at each condo unit at which point you would install a multiswitch that would control the STB calls from inside the unit coming off of one internal cable line and stb.

    4. This means you have only one line at inside the apartment at the stb (i.e. the HR10-250). However, you need a destacker between the wall line and the HR10 so that the stb sees all the signal coming from the 3 satellites. This also means that if you want multiple HD boxes, you need to have an extra line for each box since a stacked system could not handle multiple different HD calls coming from the same unit.

    What do you think?

    I think you've generally got it. The stacking confuses things a bit, but if you ignore that for a moment, there are 4 different signals that must be provided to a multiswitch so that a receiver can request the one signal it needs to tune the requested channel. A combination of DC voltage and a 22kHz tone (or lack of tone) is what is currently used to control which signal the multiswitch delivers to the receiver.

    It's possible to stack the 4 signals fed to a multiswitch using 2 cables, if cabling is a limitation, though this does require a lot of extra equipment. In a condominium/apartment setting, there are decisions to be made as to how to provide the signal to each unit. One can provide the 4 different signals and allow a multiswitch to be used in the apartment to feed any number of receivers, or one can provide the multiswitch output to the apartment, potentially limiting the apartment to a maximum of 3 or fewer tuners.... Though with 4 feeds from a multiswitch, you can feed another multiswitch.

    The choices made in expanding a single satellite system can limit you in the future. DirecTV is going to be experimenting with Ka-band delivery of HD locals in the near future and this will require additional feeds to a multiswitch (likely a new design of multiswitch), so in rewiring a building for the 110°/119° satellite, some consideration should be given to making it easy to expand further, since it's often a whole lot cheaper to run additional cable at the same time than it is to come back a year later and add more.

    Doug:

    A shot in the dark here. After your very helpful thoughts, I went out to set up an HD Tivo on my condominium's stacked system. The system has one round sattelite dish with one LNB it looks like....this is a very large dish that serves all 50 units in the condo. The system is not fully HD. All Direct TV channels are non-HD, and only the terrestrial antennae that is also stacked into the system is HD (our conversation helped me understand what we need to do to get it fully HD).

    In the Satellite closets there appears to be a switch which takes the odd and even transponders and stacks them onto one cable drop....it appears that this drop is the one that is split and amplified multiple times to distribute to units. (I don't know if this helps, but the only recommended high-def receiver from our satellite providers is the Hughes HD-HTL, and previous to my troubles here, I was using a Sony Sat B-50).

    The problem I am having is after installation of the HD Tivo with the use of a double destacker I found at 9thtee.com, the HD Tivo cannot seem to get any even transponder signal but for number 18. So install never completes as the unit can never pull the full satellite system. The install fails and says that it can't get the right side of 101(A).

    Any thoughts on what I need to do to the system so that this does not occur and I can start using the HD Tivo, albeit primarily for the non-HD Direct TV programming that I get?

    What you describe as to how the signal is put together and distributed sounds exactly like it should. When you installed the dual destacker in your home did you use any splitters? In some respects it sounds like the upper block of signals from the dish is being blocked. If you used any splitters and they weren't rated for signals up to 2GHz (typically "regular" splitters are rated up to 1GHz then there's significant drop-off above), I'd expect to see half the signals missing. But I'm surprised to see you say transponder 18 gets through; presuming it's really transponder 18.

    Looking at the spec sheet for the destacker, it's not clear if there's a DC block on the antenna side of the diplexer that's built in.

    Many people have reported strange behaviors using Terk diplexers which pass DC voltage to the antenna input, when using them with the HR10-250. They have to use a DC Block at the antenna input to the HR10-250. It might be that this is what's going on with yours. I believe if you disconnect the antenna from HR10-250's antenna input, and you can complete guided setup, then you would know this is the problem you're having and can get a DC Block at Radio Shack to place there. If you could give that a try and let us know how it goes, then we can go from there.
