Correct me if I'm wrong, but I thought "only" MPEG  and AVI files can be 
concatenated into a single file. For AVI files, you can use MEncoder's 
multiple file support like this:

mencoder -ovc copy -oac copy -o out.avi file1.avi file2.avi

This will only work if the files are of the same resolution and use the 
same codec. You can also try avidemux and avimerge (part of the 
transcode tool set).
