I had the same problem a few years ago and wrote a little program to do just 
that.
I work with digital highspeed cameras and i had to come up with a way to 
present two perspectives of the same crashtest in a single file.

I used mplayer to create folders of jpeg files and imagemagick to combine the 
images and put our company logo into the result and then reencode the files 
with mencoder. I put up a little kommander gui but the whole thing is not 
very flexible as we always have the same resolution and so on for our videos.

But this is very possible and I could offer some assistance with putting up 
the commands to merge the files.
