But with your distribution you did not have installed the mjpegtools 
before ?

Wen you go into the directory where you did run the configure and make, 
please go into the utils/.libs directory and check if there are the 
files that start with libmjpeg*

Was everything compiled sucessfully ? If not please run configure again. 
It would be interesting to find out if it was a compilor error, or 
something different.

Glad to hear, I think Ubuntu has precompiled packages.

Mplayer is your friend.

In the mjpegtools doumentation you should find the hints and examples:
http://sourceforge.net/apps/mediawiki/mjpeg/index.php?title=Creating_videos_from_other_sources

You basically have to play back the video and feed it into yuv2lav or 
mpeg2enc.

auf hoffentlich bald,
