As far as I know this is how it works, xinerama features are not
fully functional in the ATI drivers. I did some reasearch when I
first installed my ATI drivers and found that there was no fix for
it, this was quite a few months ago. I can tell you that I am still
getting the same results with xorg. Maximizing a video to both
monitors should also only disply on a single monitor, at least thats
what mine does.
I was browsing through the changelog of X.org, and I found the project
Xdmx (http://dmx.sourceforge.net/). It is used to combine multiple X
servers to one screen, usually for video-walls etc. Since the Ati
drivers have a '2 X-servers mode', I thought Xdmx might be used to
combine these two servers to one dual-screen display.
