Have you considered porting this to CCV 1.5? I’m trying to do this manually right now and I’m running into some issues.
Hi, we made a small app that may help with this calibration process : http://code.google.com/p/ltmgc .
You can select the zone of the screen to be calibrated (four side polygon only for the moment but we are thinking of including a circular shape soon).
Hope it helps!
