GUIDE is by far the best program for this sort of operation - Ive
tried them all ( I think!) and more expensive programs fail
dismally! If you are serious about optical/video tracking/positional
work then buy yourself a copy - its under $100 and worth every cent.
Visit http://www.projectpluto.com for more details. Unfortunately
there is no demo version available - but as myself and others have
found it delivers the goods. I get no commission for this - just a
very satsified user since version 2 - its now at version 8 and
comes on two CD's

I agree, guide kicks butt!
