I like your description of "green worms". Very apt. However, it sounds to me
like your connection speed is too low. At what modem rate are you
connecting, and to whom? My observation would seem to indicate that once the
picture "establishes itself" (which might take a minute or more), the "green
worms" disappear, and you can get a reasonable image. I have experimented
with 28.8, ISDN, and T1 connections. At 28.8 you can be lucky and get rid of
your worms, sometimes, but make sure you have no other demands for bandwidth
at the time you are trying to haul in the picture.

My biggest disappointment with the CQCW is the softness (sharpness)of the
picture it puts out. I run mine on the "medium" setting, but even at that
Elizabeth Taylor would have no wrinkles! :) Running sharpness on the "high"
setting seems to even further exacerbate the already huge CPU demands of the
camera, lowering the effective speed of my P150 from a 386 (running in
medium sharpness mode) to practically a 286 (when running in high sharpness
mode)... and I am exaggerating only slightly!...
