avi-io i/o buffer limit - whats that??

[droolian01]

Hi there, just starting to get set up for capturing and use avi-io with pinacle pci rave.
When doing my test captures after about 6 seconds i notice that the 'buffers used' clocks up to 50 and i get an error message to the effect that bufers are full(or something).
Up until that point the cap procedes well (no frames dropped). So now i have 4 to 6 second nice looking caps with dodgy sound(thats because of crap on board audio!!)
So can i increase the number of these buffers (can't see where to tho)
thanks
p.s. cap at pal 25 fps 352x288 pcm audio 44.1khz 16bit stereo onto ibm deskstar gxp60 60gb hd, celeron 800 >300mb ram win 98se
