A straight gender changer will NOT work.  The Amiga 1000 provides +5V, NC,
and RESET on pins 23, 24, and 25 respectively.  The Amiga 2000 provides
these signals on pins 14, 15, and 16 respectively.  Therefore you are not
supplying plus five volts to the DigiView device.

If your VCR has a rock-solid freeze frame, you can do B&W digitizing (16
shades of gray).  To do color, you have to have the camera and color
filter.  That's because DigiView digitizes RGB as 3 monochrome exposures.
A VCR cannot provide red-only, green-only, or blue-only signals.
