When I try to burn or export MOV files captured from my HD camera or camcorder, VideoStudio Pro X3 crashes.
This issue is caused by the 7.6.6 update to Quicktime.
If the 7.6.6. update is installed, exporting or burningMOV files with H.264 encoding will cause VideoStudio Pro X3 to crash.
If you uninstall the 7.6.6 update and reinstall the 7.6 version of Quicktime the problem will not happen:
You can download the 7.6 update from here.
This issue has been fixed in VideoStudio Pro X4: http://www.corel.com/servlet/Satellite/gb/en/Product/1175714228541#tabview=tab0
