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.
