Hi Ed,
Thanks for the advice.
It turned out to be an easy fix. I was AC coupling the video directly into the video amp valve using a 0.1uF capacitor. The cut-off was approx 200Hz and reducing the level of the frame sync pulses. I increased the coupling to 3uF and all is in lock now.
So, I'm slowly getting there.

regards
Craig
