Guys,
I am trying to use Cinelerra's screencapture recording function to
capture what is being displayed in the right display of my dual head
configuration.  In the Prefs -> Recording -> Display box, Cinelerra
allows you to enter the display as it is found in xorg.conf.  Depending
on the identifier of the screen in xorg.conf, this is usually comes in
the form: 
<computername>:0.0 
eg,
server:0.0

My problem is that I have an NVidia card running TwinView on dual
1280x1024 Dell flat panels.  The only identifier for the TwinView
display is 0.0, so the recording always starts on my left monitor.
However, I need to capture what is in the right monitor.  The stuff I
need to capture is output from a custom visualization software that does
not allow me to change output displays.

My thought was maybe I can just feed in a "+1280" so that the screen
capturing starts 1280 pixels to the right.  So, I looked at
recordmonitor.C and see a number of functions for the
RecordMonitorCanvas and values for position of x.  However, my chops in
C suck, so I can't figure out what to change in order to move the start
of the recording 1280 pixels to the right.  Even if I have to hard code
the value into recordmonitor.C and recompile, that is fine with me.

can anyone help?

thanks,
scott
