When I was setting up my desktop machine, I played with TwinView and Xinerama. 
I settled on Xinerama.

Xinerama
    advantages
        video overlay only first display
        rgb overlay only first display
    disadvantages
        no video overlay on second display
        no rgb overlay on second display
        no suspend on second display  (bug to be fixed)
        no opengl on second display with xinerama  (bug to be fixed)

TwinView
    advantages
        opengl can span two screens
    disadvantages
        no video overlay
        no rgb overlay
        no suspend on second display  (bug to be fixed)

My graphics card and drivers are a bit old:

nVidia Corporation NV35 [GeForce FX 5900 Ultra]
nvidia driver 7174
XFree86 Version 4.3.0.1 (Debian 4.3.0.dfsg.1-10.1unichrome30.1 20050205195924 
glaweh@)

From my testing TwinView gives opengl on both screens but you loose video 
overlay (only on models less then 6000) and rgb overlay, completely.

Probably not a help,
Paul
