Does the 30 minute cache on TiVo drive anyone else nuts?

    I want an infinite buffer. I want a Cloud hookup such that the buffer begins as soon as my subscription does and lasts as long as I subscribe to that Tivo.

    And I want all purchasers of Tivos to subsidize my needs, whether they want an infinite buffer or not.

    Plus I want a free pony.

    With a Premiere you can find a another airing of it or make a wishlist also in like 15 sec.

    My impression is that TiVo is looking for users to optimize disc space by recording content it knows we want rather than using the box to basically randomly pick up whatever happens to be on. I could see this perhaps changing this to a user selection with future larger disc sizes, but with 4 tuners the box is already allocating two precious hours to basically do nothing of direct benefit.

    Where are these ponies?

    I was with DirecTV for 14 years. The old DirecTiVo's had the same 30 minute per each tuner limit. When I upgraded to DirecTV HD-DVR's the 90 minute live buffer was kewl but also only one the current tuner. If I wanted dual tuner buffering I had to record programs on both tuners; then I could have dual buffering and the entire program; just delete when done if you don't want to keep it.

    So how exactly is that different TiVo is at least offering you dual live 30 minute buffers; if you want more you can do like you would need to do with DirecTV for dual live buffers.

    Sorry but your issue, isn't!

    They should offer options up to 90 or 120 minutes.

    actually, there is a feature with directv, i think it's called double play, that enables dual tuner, 90-minute buffering without recording, but it's a pain in the @$$ to operate, so it's of little or no use.

    I would prefer 1 hour buffer, the Virgin TiVo has this setup.

    Those aren't exactly Premiere only features.
    I could also find another airing with a series 1 or WL it with a S2.

    Sounds like it would be easier to just get the hell out of Los Angeles. Sounds like a dangerous place.

    I agree with the others that if 30 min isn't enough I hit 'record'.

    My only complaint is that, with the last updates to my Premieres, if you are watching something semi-live and it needs the tuner to record something it kills your buffer. Before I could do this and keep my buffer as it is recording something. I'm not sure I'm making sense, but I know in my head what I'm talking about. :)

    Yes, I want a longer buffer. I have a 2TB drive; space is not a problem. If others are concerned about space, it's easy enough to add an option in Settings. You may not want it; I (and others) do. Easy enough to make everyone happy.

    I am not a software person but the buffer may be in another part of the drive that as designed can't take advantage of your extra recording space that your 2Tb drive gives you, TiVo may have to allocate a fixed buffer space in this part of the drive, so having a user select the size would make no difference in available record time, in the old days when you had only 9 hours of record time adding another hour to the buffer may have cut the record time down by another hour, today that would make no difference but TiVo would have to design a new fixed buffer size, 60min or 90min. The buffer size can't change the total record time and must be allocated to the max buffer size, that today is about 12Gb/hour (or more). So with 4 tuners set to 90 min each, that would be 6 hours taken from the record time as now TiVo only has to give up 2 hours of record time. If TiVo goes to 6 tuners the buffer size would have to go to 9 hours (for a 90 min buffer) from 3 hours.

    Even on MPEG-2 FIOS, that's less than 100GB. It wouldn't work well on the smaller units, but it would work fine on something like an XL4.

    But doesn't that also describe their equipment in general? :p

    This could be consistency of the software or maybe TiVo will make this buffer bigger when going to 4Tb drives becomes possible. I agree with you that for the TP-4 units a 1 hour buffer would not make much difference, except TiVo does say that it is a 75 hour unit, it reads 76 hours, if you went to a 90 min buffer the record time would go to 74 hours.
    We get what we get, and I can live with the 30 min. buffer if it will get me dynamic tuner allocation faster.

    I suspect that the live TV buffers are dynamically allocated just like regular recordings, from the same partition space, but they are automatically de-allocated from their tail ends to reclaim the disk space. A dedicated buffer area would be an awkward complication when the user decides to record the show being buffered. The TiVo would then have to copy the dedicated buffer to the main recording area instead of just updating some directory pointers.

    Good point; but would that mean that if you had a full disk could the buffer delete some programs, what if you set all your programs KUD, the TiVo may not record any more programs when full but what would happen to the buffers ? If you filled the TiVo up when in standby mode when there are no buffers, take the TiVo out of standby, for say a TP-4, and 4 buffers start, so within 30 minutes you will need 2 hours of record space, what would give, the programs or the buffer size ? That why I thought the buffers were somewhere else on the drive.
