The problem is not audio buffer but video buffer. However, no matter
how much you increase the size, you'd just be delaying the inevitable.
Your computer is way too slow to record 768x576 video to mpeg1 in
realtime. I see you're postprocessing and scaling down to
384x288..this is a big waste of time. Just capture at 384x288 to begin
with. Or buy a faster computer.
