If you use a recent version of Vista that include Windows Movie Maker, you probably can edit Flip Mino-HD and Flip Ultra-HD clips in Windows Movie Maker.

The TRICK is to drag the clips into Movie Maker, rather than using the Movie Maker menu system to import them.  The menu system route won't offer you .MP4 files, because Movie Maker doesn't recognize that FlipShare added a new codec that it can use.

Here's an example of a movie shot with a Flip MinoHD and edited in Movie Maker. Watching it full-screen shows it off pretty well.

If this doesn't work for you, there is a way to edit Flip HD clips in Windows Movie Maker, maintaining full resolution, regardless of whether you use XP or Vista, and it is available to members here:
