    Bufferhack - What is the limit?

    Hi All,

    Just wondering, what is the limit for bufferhack?

    Currently I have mine set to 60 minutes.

    I have a tivo sitting here doing nothing, and was thinking of using it to timeshift my radio station, using live tv... Is a 12 hour buffer out of the question?

    I guess I would also need to feed a video source into the tivo else it would not recording any incoming audio? (I can just spit any old video into this.. probably a split feed from one of my cable boxes).

    Thinking of using it to timeshift 12 hours for overseas listeners of my radio station.. ie: live feed and a timeshifted -12 hour feed.

    Cheers,
    ZollyMonsta.

    I think from memory there was an issue of unstable performance after 60 minutes.... But one of the software guys may be able to clarify that. How about a string of 12 TiVo's all with an hour bufferhack :P

    Regarding having a valid video input: Yes. The TiVo will need this and yes anything will do. I once used a TiVo to record a marathon radio special and it worked perfectly with the video input from a VCR.

    Why not just image it up with the NZ image, the use the manual record function to record a 12 hour block.

    I think the idea is to have a never ending cyclic buffer to create a 12 hour delay rather than having to instruct the TiVo to play back a block recording.

    I don't use the live buffer much as I never watch live TV anymore

    But, I thought there was some issue with using it the way suggested.

    Try it with the 1 hour buffer overnight and see if you are still one hour behind by morning.

    I run 2 hour buffers on all my TiVos, and configured most of the ones I used to sell that way too... Never a problem at 2 hours, but I don't recall ever trying longer, why not just try it and see what happens?

    Cheers

    Hmm yeah.. worth a shot I think.. If it doesn't work I can always put it back to 1 hour

    Ok.. I've set it to 12 hours (720 mins) it seemed to take...though the live screen shows 1 hour.

    I went into the mfs via tivoweb and looked at:

    Directory listing of /Recording/LiveCache

    This lists:

    Name Type Id Date Time Size
    3209880 tyDb 3209880 01/05/07 13:13 488

    So I clicked on the name and it returned:

    RecordingBehavior 3209880/12 {
    DiskBehavior = 12
    PresentationBehavior = 8
    ProgramGuideBehavior = 6
    TunerBehavior = 8
    IndexUsedBy = 3209880/10

    So it looks like it's set to 12 hours (Disk Behaviour).. maybe..
    The on screen timeline might be displaying incorrectly?

    I'll leave it going for a day or so then see what it's doing.

    Something I've noticed is the skip keys don't appear to skip to the beginning of the live cache.. Is there a certain key combination to do this, rather than having to sit and wait for 12 hours (hopefully) to rewind?

    Cheers,

    Correct.. the plan is to fit another soundcard into my streaming server, and feed the audio from TiVo (rewound to beginning of live buffer.. 12 hours) so that one of my shoutcast feeds will be -12 hours of the current live program. Its so overseas listeners wherever they may be (or local listeners) can tune to that stream if they've missed a live program.

    I'm just being sneaky really, but it might just work.

    I don't twiddle with my tivos much at all anymore. In fact the one Im playing with now has been switched off since August last year.. A lot of guide data to download

    Hmm.. I could sell this second one.. but figure its probably better to hold onto it should the one in the lounge break, then I can scrounge this one for parts.
