SimpleMovieX is a little video editor from Areo Quartet that's compares nicely to Quicktime Pro (not the icky and useless QT X) and has some tricks QT Pro doesn't.
The demo version is free and mostly non-crippled: Demo version has the same feature set as full working version, except slower saving and limited number of chapter markers. There is no time limitation.
Check it out (and some screenshots) here.
Areo Quartent is the same company that does movie file repair, which has saved a few friend's projects in the past.
