I have an A3000/030/25MHz NTSC machine (also displays PAL screens of 
course).  When I tried attaching an AmiGen genlock, it fouled up PAL mode 
(when I tried running a PAL program or PAL IFF (i.e. 320x256)).  I got 
rid of the AmiGen, and now have an IV-24 (also has a genlock).  Once 
again my PAL mode is screwed up, so that the rows appear double-spaced 
and flicker.  The screen is once again fine when I change back to NTSC.

What would be causing this, and how can I fix it?

Thanks.

The genlock doesn't support PAL modes.  I don't think there is a fix for
this one.  That's why Euro-users aren't Toaster-users.  Some hardware
just isn't international :(

You can't. This is the intended function of a genlock - to 'lock' the
frequency to the external video source. Since you have an NTSC genlock, it
locks you into NTSC video modes. The only genlocks that I am aware of that
can be disabled when you don't want to use it are the GVP G-Lock and the
latest model from Play. Otherwise, as long as the genlock is attached, it
locks you into NTSC screen modes.
