I will do this, but first...

Since I don't know what you mean, I'd have to answer no. :)

I will tell you what I have done:

1. The camera I am using works (ie displays a good picture when hooked to
a TV)

2.  When I conect it to the 1881 I hook it up as follows:

The outside ring of the RCA connector gets grounded to the power supply
ground (is this correct?)

The inside pin part of the RCA connector is hooked to a 0.1 microfarad
cap, which is then connected to pin 2 of the 1881.  Additionally a
low-pass filter (as per datasheet) that consists of a 660 ohm resistor (?)
in in series with the signal, and an additional 550 picoF (?) cap to
ground.

Does this qualify as terminating the video camera?
