not long ago i came across presentavid (link). simple and nice video editor. can delete frames, add callouts, own logos & watermarks, can burn dvd automatically to watch on a dvd player and publish outputed video in different popular formats (avi, wmv, mpeg, even flash (swf/flv) and gif), also can record a screen (region, window) and then allows to edit it. exactly for those who start with all of these i guess. and also for those who don't want something very complecated.
