Just a note that a new version of ClipDown (v3.2) has been uploaded to OS4Depot. It should be moved out of the upload section soon and a news item has been submitted here.
One of the additions is a "Quit MPlayer" selection in the Project Menu. This allows you to quit playing audio streams (or video) from the menu so I don't have to open the shell window anymore to allow aborting. This makes it much nicer for streaming radio stations from sites like
ShoutCast which works quite well with ClipDown. Give it a try!
