Thanks much for your help guys. Between this thread and the thread on the e-on site I managed to sync a simple camera. Here's what I wound up doing: 1. open LW and Vue 2. in LW run Vue Pro Syncornizer 3. go to the LW content directory where VESync.dat is written and copy/move the file to the Vue 5 Infinite directory. They seem to have the path for VESync.dat hard coded in Vue -- which isn't very good coding practice. I guess I'll be manually copying the file when I want to sync cameras and lights. Thanks again for all your help, John
