Hello,

I'm trying to grab a 640x480 BW frame as fast as possible, itcurrently takes roughly 100milliseconds per grab. The live video feedstraight to the monitor runs smoothly at 60fps though, shouldn't a framegrab be 17 milliseconds? Is there a way to boost the frame grab rate?I only need to grab a couple of frames, its just that I want the grab tooccur very quickly.

   Thanks
      Andrew
