what do you use instead of Xinerama?

So I guess you're not using Virtual in the “Display” SubSection in

If you record (using Xnee) when you move your mouse/pointer from top
left on left monitor to bottom right on right monitor. Does Xnee record

Xnee replays to one display.

I am not sure what you mean?

Xnee gets copies of the data (such as events) sent and received by the X
server on one display. So the X server copies the communication and
gives Xnee the copies.

At the moment we're not considering multiple display (same server)
functionality. There's no time for that at the moment. Would this solve
your problem?
