Is there any way to disable the QuickTime preview of .avi files in column view? QuickTime's compatibility with AVI's is absolutely appalling, and so every time I select an AVI in column view, it comes up with a dialog saying "QuickTime is missing software required to perform this operation. Unfortunately, it is not available on the QuickTime server". I mostly use VLC to view AVI files, and I have VLC as the default program to open them, but the finder insists on trying to open the preview with QuickTime. Is there any way to turn off previewing for just AVI files, and if not, is there a way to disable previews altogether?
