I’m running Mac OS X 10.6.6.

I have tried the popular method of merging the files with QuickTime, but it’s not working. Is there a free way to do this?

    Here's the cat command you can run in terminal http://www.junasoftware.com/blog/how-to-join-multiple-mpeg-video-files-on-osx.aspx , seems to work fine for me.

    The easiest method I know of is using MKVTools
    http://www.emmgunn.com/mokgvm2dvd/mokgvmdownload.html
    - open MKVTools
    - click on the "Tools" tab and select "join"
    - drag the MP4 files you want to combine into the squared drop section

    If you want more controle and options you might you probably have to spend money on a decent media converter/tool:

    QuickTime X doesn't have the full functionality of QuickTime Pro. You would (most likely) have to install QuickTime 7 from your Mac OS X DVD or from the Apple Homepage and get a license for QuickTime Pro.

    Join MP4 files using MKVTools
    http://www.emmgunn.com/mokgvm2dvd/mokgvmdownload.html
    - open MKVTools
    - click on the Tools tab and select join
    - simply drag the mp4 files into the square box where it says "Drop mp4 files here..."

    If you want more options you probably have to pay for a decent software
