Best way to merge mp4 files Got a bunch of .mp4 videos (info shows H.264 Video + AAC Audio) that are chapters of a larger video.

I'd like to merge them, but not sure which is the best way.  I don't have Quicktime Pro, but I'll get it if that's the best way to do this.

Edit: Just to clariify this is Mac OSX 10.6 I'm on.
You don’t specify your OS but if you have OS/X, then you probably have iLife, then you have iMovie. Merging all that with iMovie is extremely trivial. Just import the videos to iMovie and compose the final movie using all the parts you want to use. 

Effects, Transitions and Captions are a bonus ;)
