I have been using Ulead Video Studio 11 and also downloaded Corel Video Studio Pro X3. But both applications are making problems when I am taking a preview of a ‘.mov’ project file. The Sample files are previewing properly in both applications but when I am adding a ‘.mov’ file to the timeline, it gives me an error message which says “The program encountered an error and forced to quit. Please contact support and “.dmp” files.” I have lots of ‘.dmp’ files. And also, when I am trying to add an audio file to the project, it keeps hanging. How can I run your program with the Canon SX20 IS camera? The video format is ‘.mov’ and I need to run with the application. My computer uses Windows 7 and the browser is Internet Explorer. I also downloaded the trial version of Video Studio Pro X3 but the problem remains. Please help me to get out of this problem. I will thankful for all help.
