In your case may I suppose you're using GNOME?
I think there's a place where you assign default apps (System Settings? gnome-tweak-tool?).
You could try the xdg-mime method maybe with:

xdg-mime default mozilla-thunderbird.desktop text/calendar

If you start the file manager, "Thunar", and then right click on the X.mov file pick "Open with" and then "Open with other Application" you should be able to choose vlc and that choice should stick for all .mov files.

I have somewhat of a similar problem to this, I have Thunderbird installed on Fedora 17, and in the "Details" tab ofthe "System Details" where it lists the default applications for various types of files, I have:

Web: Firefox
Mail: Thunderbird
Calendar: Software Install???!!!
Music: Clementine
Video: Movie Player
Photos: Image Viewer

How do I change the (obviously!) incorrect assignment of Software Install for viewing / opening Calendar? Bear in mind I already have "Lightning" installed as a Thunderbird Add-on.....so I can already view and manipulate my calendar through TB's interface....but HOW and WHY did Software Install assign itself to that task?...and how do I undo this? It's not hampering my usage of the PC in any way, it's just annoying....


Thanks!
