I never noticed this until now with the Quicktime 7.4 (and I'm using Tiger). Open a movie in QuickTime Player. Now drag and drop another movie onto the player window. (I wanted to open and play the second movie, but it didn't work.) When I tried to close the QuickTime Player window, I was asked if I wanted to save my changes. I did save it to see if I'd get the "This feature requires Quicktime Pro..." notice, but it just saved and closed.I reopened the movie and the two movies have been merged into one file.[robg adds: I can confirm this works without QT Pro, but note that it will overwrite the original file, with no chance to rename it before saving.]
