    Yeah, I'm not sure how I'll get the thing in the attic. It's not huge, but it's big enough to make me think this isn't going to be easy. I checked again and NBC is on VHF, so I guess I'll have to get some kind of VHF antenna too.

    I bet a lot of people don't bother with all of this setup. Especially those who just want to bring their TV home and plug it in. It will be nice when/if DirecTV offers HD locals. At least that will simplify things a bit.

    Gromit, I tend to agree that a lot of people will not want to go through the hassles to receive OTA HD signals. DirecTV is going to probably have to start including that as part of HD installation deals (in parts of the country where it's possible to receive HD channels via antenna), or provide the locals via satellite, as you mentioned.

    You could also get a yagi antenna, that has both UHF and VHF elements on it you can check out some of the different ones available at www.starkelectronic.com

    and the whole antenna thing can be a total pain in the rear, I do installations on the side and it can be a real challenge in certain situations. Installing wiring for ethernet, phone, cable, satellite, etc. is just so much easier than dealing with an antenna but for some, like me, it's a necessary evil.

    The 4228 can be disassembled a bit to get it through smaller openings if you have to.

    I've been reading a lot here is the HD-TiVo section the last hew days, but have one question that I haven't seen addressed, or even asked. It may well be that we simply don't know the answer yet.

    Will activation of the HD DTiVo require subscription to an HD programming package from DirecTV? Or can I use is it strictly with SD DirecTV and Digital OTA programming?

    Essentially, can I get one without having to change my monthly subscription costs, other than add a mirroring fee? I fully expect to see a 12 month commitment to remain a DirecTV customer.

    Neither the VE or GG preorders said anything about having to add the HD package, though I suspect that DirecTV is thinking that people will, and that after they figure out that people aren't that they will require an HD premium for at least a year. (HBO, Showtime, or the HD package.)

    They want people to subscribe so they have money to add more stuff, or at least that is how I see it.

    That will probably get it through the entrance to my attic (pull down stairs, standard size I suppose). Since I have to pull in 1 VHF channel too though, I'll check out the yagi that llogan mentioned.



    I figured the HD package was a requirement to get the free dish upgrade. I'll need the dish but I figured HBO and the other HD channels will be worth it. I might even be able to sit through hockey on HDNet. :)

    Subscription to DIRECTV's HD programming package is not required.

    In fact, you will get the following HD channels, HBO, SHOWTIME, *CBS and *FOX, at no additional charge, if you subscribe to the respective SD programming.

    * CBS and *FOX HD channels are available in the 16 O&O markets only.

    Sorry, I'm really confused. There are 3 satellites, 3 LNBs. I'm okay with this. I'm guessing that with 3 LNBs you have 3 cables out of the dish, right? Now the HD-DVR250 says it supports 2 digital satellites and I think it has 2 connectors for this. How do you go from 3 LNBs to 2 satellite inputs?

    Now my head is really spinning. How did we go from 3 LNBs to 4 LNB signals?

    Lastly, is there a simple tutorial on switches? Something I can read to help me make sense of the above quote?

    The Phase III 3-LNB dish has a built-in multiswitch, which outputs 4 cables. You can run those 4 outputs into a 4x8 multiswitch, which will give you enough outputs to support up to 4 DirecTivos if you'd like.

    Well, it doesn't really work quite like that. Technically, for each LNB, you need two cables, one for even transponders, and one for odd, because a single cable can't contain both at the same time (Except the Sat-C, or 110 LNB, which only has even transponders). BUT, because they only have a handful of transponders on 110 & 119, they "mix" the even transponders from 110 in with the 119 transponders. THATS why there's four cables: two for 101, and two for the mixed 110/119 signals. A cable can only carry one of the four "sets" of signals at one time, and that is the purpose of the multiswitch: To give each receiver the right set. So, with the four outputs from the Phase 3 dish, there are enough for each cable to be dedicated to one set, and the multiswitch connects each output to each receiver to the right input, depending on which set it requests.

    The two inputs on the TiVo have nothing to do with any of this: for all intents and purposes, it is two separate DirecTV receivers (it has two tuners, to tune to two different channels at one time, even if they are on different satellites). Therefore, it needs two separate inputs from the multiswitch.

    Many thanks Darin. My current dish has the switch built in so I had forgotten about all of this. Interesting that you pretty much HAVE to have a switch with a dish now.

    A 3LNB dish sees the 3 satellites.

    The FOUR wires that come out of the dish are all "switched" outputs which means that any of the 4 wires can see either side of any of the 3 satellites.

    This is why you cannot use a splitter, because signal tones and voltages are sent up the wire FROM the DirecTV receiver TO the dish (or multiswitch) asking for the satellite feed they need to display the requested channel.

    Ok, I've updated the FAQ. How's every 2 days? :D

    I've added my 3 sentence description of multiswitches above as well as 2 new HDTiVo-specific diagrams which should explain all permutations of 4xX and 2xX switches.

    Hmm, if this is true why would need need a switch if you only had two TiVos??

    Because for 2 TiVos, you need 4 inputs (tuners) which can each see either the even or odd side of the 101 satellite depending on what channel you're watching/recording?

    You can't get all of the 101 satellite on 1 wire without stacking. The fact that you only need 101 odd and 101 even allows you to use a 2x4, 2x6, or 2x8 multiswitch (as diagrammed) to feed DirecTV TiVos.

    For 101/110/119, you need a 4x? multiswitch.

    *IF* you have the 3LNB dish with the integrated multiswitch (4x4), and you only want to use 2 TiVo's, you're all set. No additional multiswitch required.

    That sounds good. I'll have 2 TiVos, so I guess I won't need another multiswitch.

    Under this scenario, I guess the OTA antenna goes directly to the HD TiVo? If you have a multi-switch with an OTA input, can you go that route as well? Does the OTA signal then go to each of the 2 lines going to each TiVo? If that's an option, I'll have to decide if I want to avoid drilling another hole in the side of my house and go the multi-switch option or just run the OTA directly into the house. My 2 story family room makes it difficult to run a line from the attic to the room through the walls. I pretty much have to go outside and into the family room via a drilled hole.

    Maybe the future for HDTV TiVo is Serial ATA?
