This one is a strange one. I can import MP4 HD video file from my Sanyo Xacti video cam to PSE 9 Organizer, play it, send it to Premier Elements, edit and burn it to a disc then close and reopen PSE 9 with no problems but after I have closed PSE for some time (5 to 10 mintutes) and reopen it, the thumbnail in the Organizer is just the hourglass and Organizer will crash. From there, I need to go to Premier Elements, start a new project and delete the thumbnail, not the entire file, before I can again open PSE successfully. Running Win 7. Any ideas ?
Where is the file physically located, on you internal HDD?
yes, it is on my internal. I have never had this problem before when I have uploaded my AVI files but I just got an HD camera and this has happened since my first upload of MP4's.
