Recently I have updated to Quicktime version 10.7. The problem is I can no more export the .wmv file(s) using Quicktime 10.1. The problem was with the Flip4Mac as it was not working properly with QuickTime version 10.7. This problem was not solved even after when I opened the .wmv file and save it with .mov format in QuickTime 10.1. I keep getting the message 'Cannot Open This media may be damaged.' Has anyone has these same issue or would like to tell the why it happens?
