I've currently set my default player to vlc but now as ive discovered mplayer and find it to be more useful than vlc, how do i change it to become the default program to run .*avi files? I've tried going to the *.avi file and command + i and tried changing it to mplayer, but mplayer doesnt seem to like being default and it always hops back to vlc. Appreciated if anybody can help me solve this. Many thanks before hand....
