Is this a new phenomenon?
When you "manipulate the menu", do you mean the vic menu(s) on the
capture machine itself, or the "Manage my Node" menu (back on the
display machine) to configure vic via VideoProducer instance(s)?
What frame rate are you attempting? For PAL, 24fps is usually the max
for standard composite/s-video bt878 capture boards, rather than the
expected 25fps. Perhaps there's a similar problem for NTSC (try using
29fps, rather than the expected 30fps)? Also, any USB camera running
with 2.4.x kernels is _very_ inefficient, and will cause the symptoms
you describe, at greater than 21fps.
Any other apps running on the capture machine chewing up cpu cycles?
Are other applications on the capture machine affected the same way
(slow to respond)?
