And a second possibility / try:

What happens if you try to load the zoran kernel module with the
option "v4l_bufsize=700"? It seems, that the default buffer size is
set to 128k, which, if this is really right, is quite small.

Or, alternatively, set the Downsampling in iceWing to 3 BEFORE iceWing
accesses the grabber for example by starting iceWing with
  -rc "Other.Downsampling=3"

Bye,
