[jitter] buffer live video up to 30 minutes

Charles

as a follow up to our off-line discussion, here are the details of my  
recipe for XP.
you need a RAM disk of at least 4 times the segment size.

recording:
WinDV records to RAM disk. make it write file segments of 25*60  
frames or so.
in your max patch, [folder] polls the RAM disk and when a segment is  
completed,
[doshack] copies the file to the hard drive and deletes it from the  
RAM disk.

playback:
two [jit.qt.movie]s alternatingly play a segment from RAM disk.
just before a new segment needs to come up, [doshack] copies it from  
the hard disk to the RAM disk.
when the one player has reached the end of its segment, the other  
player reads the new segment and
you begin sending bangs to the other player.
[doshack] deletes the previous segment from the RAM disk

with this set up, the transition from one segment to the other is  
hardly noticeable,
even when the recording is in progress. This was on a dual core machine.

If you would go for a solid state drive, I expect that you can do  
without the RAM disk,
but I have not yet tried it.
