More than half my files not showing up in Media Bay


I’m using 6.5.4 on Snow Leopard.

In the media bay when I click on a folder( many many folders actually) that contain audio files (wav and aif) absolutely nothing shows up in the window. I have to uset he Finder to go to those folders and audition and drag the files from there.

WHat’s up with this?

I have no search criteria up and I am using the All Media Types filter.
