    The best explanation of it to someone who has never had a tivo is to put them in front of a tivo that has filled its buffer and let them watch it back up to the beginning of the buffer. Most people will grasp the concept within a few minutes this way. It's the old picture/1000 words thing.

    Maybe this is not the place but since it is about the rolling buffer and live tv...

    On an S3 are there TWO rolling buffers or only the channel that was last tuned?

    My understanding is 2. Both channels that the tuner is camped on are rolling. Yes?

    Yes, it is true. yet, my medium is confined to print. Must create the picture with words this time.

    Maybe I'll inspire some on my committee to buy one and get the full picture!

    Yes - each tuner (there are 2 of them) has a "rolling buffer" of the last 30 minutes aired. When the channel is changed on either tuner, the buffer associated with that tuner is cleared and a new buffer is begun.

    Yes, two live rolling buffers. And it's quite handy. You can pause one buffer, speed thru the other one (like watch the news in 5 minutes), then come back to the first buffer, and do it again. I can keep two sports events going, or news, or late night TV, or whatever. Very handy! :up:

    OK, here ya go:

    It's like a 30 minute 8-track tape, except with video and audio, with the playback head just prior to the record head.

    :D

    And there is the nice feature that the "rolling buffer" can be included in the recording if you chose to record the currently-showing program. If you are less than 30 minutes into the program, it will only include that part associated with the current program (and toss the rest).

    Yeah, I like that a lot, and I've done it a lot. I love the buffers!

    Wait...isn't it more like putting a 33 1/3 RPM record on and then rotating it backwards to get the hidden messages they put there? I'm sure I can see the devil when I rewind TiVo sometimes. :eek:

    Now where's my tinfoil hat...I know they can hear my thoughts. :D

    Not from my experience. If you are less that 30 minutes into a show you get the entire buffer including the part that was previous to the current show. I'm not sure if I've tested this yet on my S3's or THD, but my directivo's always gave be the full buffer in a recording like this.

    I think that this is a difference between the direcTivos and the standalones. I've seen my S2 crop the pre-program part of the buffer.

    In computer programming texts, they used call the concept a circular buffer or ring buffer. Perhaps some prefer the rolling buffer term because it sounds more dynamic, it could also imply a steadiness to the data rate (rolling along).
