I am using Movie Edit Pro MX on an HP Pavilion Elite HPE-210f Desktop, AMD Phenom II X4 945, 8gb PC3-10600 ram, ATI Radeon HD5450, 1TB 5400rpm SATA (750gb free)... I am unable to export any movie to a file. I have tried avi, mpeg2, quicktime, windows media, uncompressed, etc. Each time it starts and after 20-30 seconds will stop and give an error that the export was unsuccessful. Try a different export file type or check to see if you have enough hard drive space. The video is not even 4 minutes long. I can burn the video to DVD just fine, but will not let me export to a file. I never had an issue with Movie Edit Pro 14. Any suggestions?
