Cinelerra works fine with 'normal' dual head setup and not xinerama.
That is, one Xserver driving 2 (or more) independent displays.
Advantages disadvantages:
+ Displays can have very diffrent resolutions/color depths
+ Almost all window managers handle it right
- You cant move windows between the screens
- Windows can't span screens
Configured is it somewhat like following (xorg.conf):

Note that I used the the nvidia tool to set this up, but should be
doable manually with other cards as well.
After that you go to cinelerras preferences and change "Display for
Compositor" to ":0.1" .. that is server 0, screen 1, restart cin and it
should work.
Alternatively it might be possible to start 2 xservers, but likely a
waste of resources and not much easier to setup. Then you enter "Display
for Compositor" to ":1" in cinelerras preferences.
Btw anyone have a modeline to drive a 2nd screen in PAL mode? that would
be interesting for Fullscreen editing ... or even make a 3rd screen
which is then the 'S-Video' output of the graphic card driven in PAL.
That should give exact video preview \o/.
