[comp.sys.amiga] Progen/A500 problems

I am posting this for a friend, but I have a vested interest in it's
outcome....
 
The setup: An Amiga 500 with 1meg, external drive and a Progen. I believe he
has a 1084 monitor. 
 
The Problem:
When the Progen is used, and external video is fed in, we are getting subtle
bars (shadows) across the computer generated portion of the video. The "live"
portion is not affected.  When a solid background is used, the bars appear
across all of it. The A500 is normally part of an SVHS editing system, but even
when the Progen is fed video directly from a camera, the problem surfaces. The
Progen is fine, since we have tried it with my 2000. In fact, it looks damn
nice for what it costs. We both have come to the conclusion that is something
strange about the A500's RGB output in relation to the 2000, since the A500's
composite output looks fine.  
 
Any suggestions would be appreciated. We would both like to get down to serious
work with this setup.
