    Same here. There's been a few times when my wife turns the TV on and sees an interesting special on. She'll hit record, but if the show started more than a half-hour prior, then the Tivo can't get all of that show even though the tuner has been on that station the whole time.

    Because the shows in question tends to be non-repeating specials, we discover them spontaneously. It's not as if I can set up a wish list for that.

    For the situations we run into, a 1-hour buffer wold cover most of them.

    Unless TiVo's programmers bungled the design originally, increasing the length of the buffers should require only a few hours of some programmer's time. It should be just a matter of changing something (a data constant one would hope) that specifies how long video data takes to age out and be deallocated. Making this a user option would require menu programming, which would take more work, but even that shouldn't be too difficult.

    Because I watch so much TV that everything I have recorded I already watched at the moment.

    There are only two times of the year when I use live TV:

    At the end of the fall season before the summer seasons starts.

    At the end of the summer season before the new fall season starts.

    Sometimes I don't know what I want to watch and need to explore live TV for something new, granted the second I find something I hit record and come back 15 minutes later.

    I really only watch live TV if I am waiting for another show to record enough for me to skip commercials.

    The Advantages = Finding a show TiVo didn't recommend to me. Especially helpful if you start watching a new genera. Like when I started getting in shows like Ancient Aliens.

    I have my shows picked out before the fall season starts . I watch the trailers and then setup some SPs to watch. Of course I delete most of them.

    You are missing the point here. He doesn't watch nor care sports. POINT NULL AND VOID. :D

    What I don't understand is why there are people on this forum who always are against any kind of change, even if it could be done in a way that wouldn't affect them.

    OK, so you don't think you would need a longer buffer. You claim you always record anything you might be interested in watching. That's great. But TiVo could very easily make it an option where the user could select, for example, none, 30 min, 1 hour or 2 hours. Very simple thing to do and would make many users very happy.

    All of you that don't think a buffer longer than 30 minutes, or one doesn't reset every time the tuner is changed to another channel, would be useful, can keep it exactly like it is. For those of us who would like options, we would get to use it like we wish.

    Now maybe I am off base. Maybe there is a crucial reason that would kill the performance of the unit as to why TiVo does not allow a longer buffer. I have yet to hear anything like that though. If someone can enlighten me, I would love to hear from you.

    Maybe they do plan on enabling a longer buffer option? But on the "to do" list it's right below converting all the screens to HD.
    Maybe it will be an option on an S5 box?

    I think quite a few users have been asking for this for many years. Like I said, it's a very simple to implement.

    And please don't talk about an S5, I just got a Premiere Elite. lol

    Just because someone says it is easy to implement does not make it easy to implement. My guess is that if it were so easy, it would already be in the queue.

    This kind of change is a detail, especially considering how long it has been in place. While I, and others, understand how some use the buffer (especially those coming from other DVRs), many of us prefer that TiVo utilize their limited resources to address some of the basics and more important features before adding such a specialty item.

    I don't have any issue with anyone wanting this. But I would want TiVo to work on other things first.

    I think people say "easy" because were asking to increase the level of a current feature not ad a new one from scratch.

    I would love to know what would needs to actually happen to increase the size. There is probably a very good simple reason to why the limit it to 30 minutes, hard drive lifespan might play into it for all I know.

    I am just speculating mind you, as a web developer I completely understand how something trivial may sound easy but really it requires upgrading 5 core system components.

    Just to set lrhorer off again, it seems to me that those who are green (i.e. trying to save every last bit of energy usage) would like a zero buffer option or something like that.
    A mode in which a non-recording, non-playing TiVo isn't buffering at all and is in the lowest power down mode waiting for (a) a show to record, or (b) user interaction.

    No one is claiming that choices are a bad idea.

    No one is begrudging anyone anything.

    The point that is being missed is that the inevitable result of using live buffers is taking a longer time to watch less TV. One can say or believe one wants something, but when that thing inevitably results in uinintended consequences, then no matter what one believes, one doesn't actually want what one thinks one wants.

    Let me cut to the chase, however, and be done with it. Opinions, analyses, wants and desire are all irrelevant to the original question at hand.

    Those who say they want an extended buffer have presicely four options:

    1. Continue to moan and complain and hope TiVo comes around to their way of thinking.

    2. Suffer in silence and hope TiVo comes around to their way of thinking.

    3. Abandon the Tivo.

    4. Investigate the things others of us have suggested and maybe - just maybe - find the buffer is neither as necessary or as desirable as one originally believed. Then, if in the long run it turns out not to be true, one can always revisit number 1, 2, or 3.

    In the mean time, those of us who have taken the small amount of mental effort required by #4 are very happy with what we have. How many of you on the other side of the fence are happy with #1 or #3?

    Pittsburgh,...
    Thank you! I had no idea that despite using 5 different models of DVRs over the past 13 years, I was but an idiotic "duffer", as you say. Why, just look at my meager post count! I guess I must not be as dumb as that person with 11 posts you pointed out earlier, but I'm still like 100 times dumber than you. Well, I'm not sure about that - numbers are not my strong suit. BTW, I have had people call me an "engineer" but in real life I just write code and I've never even driven a train so I'm at a complete loss to explain that one. (?)

    So, can I please hire you to come to my house and set up my Tivos properly so I never have to be stuck watching sub-optimal TV again? If you could teach me the secret of how to be so absolutely sure about my way of thinking that I know for certain that it applies to every other living person, I'd gladly pay extra.

    Thanks again!

    Well, it's probable that spinning a drive up and down that often is bad for the drive. And isn't it "greener" to have the drive last longer than to save a miniscule amount of power? Plus, a net connected TiVo checks in fairly often with the mother ship. OTOH, even if the drive were still spinning, it might save a little wear and tear on the head actuator mechanism if weren't recording. I think this is exactly what the old DTiVos did when placed in "standby".

    What do you mean? The drive never stops spinning so long as the box is connected to power.

    He was replying to my "feature suggestion" that one option for the TiVo Software team is for a "green" mode that powers down when not in use. (I haven't measured my Premiers' power draw yet)
    If one records and watches 2 hr a day, the TiVo would be running 24 hours but used for 4. So whatever the power draw is now, it would be close to 1/6 in that mode.

    As is often the case, lpwcomp points to a fact, the start/stop of a drive is more wear and tear on the drive.

    I counter with the wear on all components inside the TiVo. Electronics lifetime is related as well to the number of hours they are in use, and processors in particular run hotter when in full use than in the low power (idle, sleep,snooze,doze, whatever) modes. So it's an exercise for the reader to understand the tradeoffs.

    Easier to replace drive than most anything on the mother board. (IMHO)

    As is often the case, people seize on one part of a post and ignore the rest.

    I will counter with:

    1. that I also pointed out that:
    a. if the intent is to be "green", replacing the hard drive more often is wasting more resources than you save.
    b. a net connected TiVo would have to wake up quite often to contact the mother ship

    2. a TiVo mb rarely fails.

    3. While the drive is the most easily replaced component, it is also the one most likely to fail anyway.

    I will also add that if you put all of the tuners on channels you don't receive, it probably stops recording, thus emulating the behavior of the old DTiVos.

    Sorry. Really. Yes, I focused on the tradeoff I saw. Your points are well taken, regardless of each and every point, my proposal has flaws.

    There are government regulations (overseas, I know for sure) that non-used systems (say a clock radio that's off) can only draw so much power. I starting with the premiss that the buffering TiVo would take more power than the lowest mode one can imagine.

    My 'often the case' wasn't sarcasm, by the way. You pointed out something I hadn't considered, and it would be pretty bad to have drives failing at 10X the rate due to an attempt to save power. Obviously the other points need addressing as well. No green TiVo for me today.

    Sorry if I seemed a bit sensitive. I've been dealing with other posters in other threads who do exactly what I was complaining about.

    Actually, the main reason for my post was to avoid making one (that I actually composed) that was an indirect response to a certain other poster on this thread who shall remain nameless. I decided to take my own advice and ignore him.:cool:
