Just updated to 7.5.10 and now when I go to the import a QT video into the Project Pool window to get both the audio to work on and the video to see. I can't import. When I highlight the file in the finder window after hitting 'import' at the top of the pool window. The info line that usually tells you the sampling rate, bit rate, etc. only says:
Invalid or not supported file.
I was working on an audio track derived the same mov file before in 7.5 but decided to start over in the new version.
so I know it worked before.
I also tried with other .mov tracks and the same thing happend.
I hope this gets fixed pronto...
