It'd help to know what software you're running. In many wm's, wizards
watch devices and pop up running what they decide is the most
appropriate application. Depending on whether you'd like to list the
contents of a media or play that media, it may or may not do what you
want at the time.
You can ignore/disable them and do it manually for more control (and
possibly less confusion).
