[comp.sys.mac] Composite Video Adapter

We received a video-board for the mac+ from Open Mac Enterprises.
The installation is pretty simple. But we disUnt get a proper (NTSC) 
composite video-signal out. There seem to be 3 or 4 overlayed pictures.
Could this be due to  60-50 Hz incompatibility? Does anybody know
a fix?
