It is entirely impossible for VNC to capture the video overlay from
the FAST Video Machine.  If I recall correctly (we have a FAST Movie
Machine and, I believe, a Video Machine as well), these are ISA cards
that use a VGA pass-through cable for overlay purposes.  Because of
the VGA pass-through, there is no way for VNC to ever capture that
video.  You would need a PCI based video capture system that did video
overlay directly into the frame buffer on the display adapter, such as
a Miro DC30 or DV500.  We have both of these video capture systems,
but I have never tried VNC with them.  I do not know if it would work,
but it has a much better chance.
