I think this has probably been posted before, but I couldn't find any solutions that worked for me. My Open With... menu has multiple entries of apps. Example; Right click .avi file, open with... VLC, Quicktime, Other, VLC, Quicktime, Other and over and over it goes. I have rebuilt the LaunchServices database with Onyx, and this didn't work. I have also deleted the LaunchServices.plist file. Any thoughts? Thanks in advance to anyone that can help.
