after upgrading QT to 7.1.3 whenever I play a movie throught QT the volume slider starts moving by itself to the left intil I can't hear anymore??? whats going on??? With VLC it plays fine, and the funny thing is when I go to the " open with " window I see " Undo Sorenson Adjust Audio " ??? Thinking this is the problem I choose to undo but then I get a message saying " Audio doesn't appear to have been offset for Sorenson v3 b-frames. Aborting. " I just opened up Adobe Photoshop when I went to choose a color it was moving by itself??? what in the world is going on APPLE!!??
