you did Share in iMovie to the socalled MediaBrowser.
that MediaBrowser allows to share all Project btw all iApps.
but it is no real, single 'folder'.
as you noticed, shared Projects are within the Project-file
if your Project is shared/published, there's a lil' icon (lower arrow)
to remove, goto Share again
select Remove from
select where you like it to be removed, e.g. from the MediaBrowser
poof! - gone
never, NEVER erase or move any files or folders of iM in Finder!
iMovie (iPhoto, iTunes) are basicly data-base.apps - you kill the internal file-management, when doing any operation outside the app(s).
